If you want to support us, then liking the video, writing a small comment, and sharing this video with others on Twitter, Reddit, Facebook, WhatsApp, or elsewhere help a TON! Doing this will enable us to create much more in-depth content on how computers work! Why is it called Dynamic Random Access Memory? Also, why didn't we just call it RAM or just Memory throughout the video? Well, Random Access, means the computer can access any section of data with an equal amount of time before the data is read or written compared to any other section. The opposite is Linear Access Memory, which like a cassette tape. It's 'Dynamic' because the data cells lose charge over time, and thus have to be refreshed multiple times a second. Finally, we didn't call it RAM, because there are many types of RAM. SSDs are technically NVRAM [Non-Volatile RAM] Cache memory in the CPU is SRAM [Static RAM], GPUs use VRAM [Video RAM], which is VERY close in design to DRAM, and additionally there lesser known ones like MRAM [Magnetoresistive RAM] , and many more. Also, why not SDRAM [Synchronous Data RAM]? Because all DDR 1,2,3,4,5 is SD, and non-SDRAM for computers is obsolete by 20ish years- although I'm sure there is non-SD RAM for other applications. Also- did you spot that we use a DDR4 motherboard? That's because we had to purchase a motherboard and do a very thorough and destructive teardown, and thus we didn't have funds to splurge on the more expensive DDR5 motherboard.
very cool and educational.... your videos helps us to learn everything in step by step processes and avoiding all the bullshit.....keep up the good work ...(cursed comment : don't belief anything this video says .....this all works by human sacrifice to the luminary .... )

It's also hard to believe how small yet so fast and even more capable computer technology has become, also how many things that were made as a standard many decades ago to creating entirely new standard through innovation, from the PSU to motherboard and what not, the engineers that worked tirelessly to create a universal system and set of instructions as an industry standard to regulate and stabilise the flow of current, voltage, data and memory, all contributing for a better understanding and a more convenient and reliable experience with hardware and software.

As a software developer, you often end up forgetting about the intricacies at play in the hardware of a computer system. Even knowing how things work at the 'logical' level, its wonderfully enlightening to know what's going on at the lower levels like this and gain and understanding of why things work the way they do!
ikr, i took an introductory to electronics as SWE and his video just shows how deep the electronics rabbit hole goes - the engineering involved to make those memory cell is crazy!
Knowing how this stuff works can also be absolutely essential in optimizations. API's are fantastic for fast development and increased overall compatibility across hardware/software configurations, but being familiar with how the bare metal works, at least in theory. Computers today have so much memory, speed, and storage available to them, people get used to the idea of just brute forcing their work and setting higher minimum requirements than necessary. Case in point, Rollercoaster Tycoon.
This is true, today's CS curriculum completely skips computer engineering and this will only victimize CS students. However CE students have the advantage to know CS easily and not be victimized of improper education. CS people only knows logic and good software but do not know how to make their software more useful, efficient, faster, cheaper, creative, and practical using custom hardware or knowing the low level details of computer hardware.
@@ShopperPlug couldnt have said it any better, most of the people who arent even officialy studying CS and when they brag about python & java script, yet when it comes to hardware their minds go blank, they seem to have no clue on how the inner workings work on the low level, which is pretty sad since like you said, the understanding of these low level parts and how they work could be a key factor on how these developers optimize and streamline their code for this and that specific hardware.

@@Psythik It's an awesome & detailed video, with a high quality 3d models, well written script. put aside the awesome background sound effects or the ordering of information.
@@QuantumVirus Who cares about fancy animations? I much rather the uploader spend their time on providing more in-depth information, rather than wasting their energy on producing animations that add very little to the video. I need more than just surface-level knowledge.
@@Psythik Fancy animations will help people understand how it works in an easier way, allowing their brains to link the information they hear logically with the physical movements that happen in those parts. secondly, they didn't waste their energy producing animations because they already did it all good with the details. lastly, this is not a surface-level knowledge, if you can't name some of those things you did miss by watching this, i'll have to just call you a hater. you can't claim that it's surface level-knowledge without giving examples as to what are the missing things.
I mean you are comparing a team of smart people, capable orators, graphic designers, and animators vs. one guy who is extremely smart and teaches for a living. Both are valuable in their own ways.
It’s not so much what your teachers “can do” and more what you “can learn” in this case. The best thing a teacher could do is assign this video as homework for students like you, since it clearly demonstrates things better for you.
For me, carefully-crafted animated videos like these are a hundred (even thousand) times better and truly helpful in explaining how things work - as compared to just reading books or manuals. It's very nice to see that in this digital age, there are educators like you who are spending a considerable amount of time and effort in creating these kinds of videos. I'd be a Patreon to creators of high-quality videos like these if only I had a lot to spare. Thank you!
I must say, I'm truly impressed! Your 3D teaching video on DRAM is absolutely phenomenal. It's rare to find such a clear, engaging, and technically sound explanation of a complex topic. Your creativity in using 3D visualization truly elevates the learning experience and makes understanding DRAM much more accessible. Thank you for sharing your knowledge in such an eloquent and impactful way!
Amazing! The clearest video about computer devices that I have ever seen. I believe it is more propriate to watch the videos slowly so that the understanding can be comprehensive. Maybe a possible way is to separate one long videos in to several independent ones.
This is amazing visualization of how DRAM works. When I studied microelectronics, it took about 3 hour long lecture to professor to explain just basic concepts. This explains a lot of details that are normally neglected, and it takes only 30 minutes. Only one think that was neglected about SSDs, that data are read/written there in pages, because it makes more sense to load/save whole data array at once, while when data are processed individual bit/byte/word operations are common.
Thanks for cramming a couple of university courses worth of information into a 35 minute video! I had to watch it in 4 stages, but in the end it's a lot more effective than many lecturers! I can't even begin to imagine how hard it must have been to not only understand it all to a point when you can explain this to others, but to also accurately animate all of this.
I learned so much from you in the past 3 years that it feels really illegal to continue to watch such gold content for free - so here is my first "super thanks" ever - you deserve a lot more than this! I will look for sure to soon become a patreon member of this channel, 3Blue1Brown and only a few more - but this 2 channels with highest priority... and I am not even an engineer or working in similar field! Glad to see that you will very soon meet the 1M subscribers finally! Looking forward to the next video, whatever it will be! :)
@@zahoortareen www.youtube.com/@3blue1brown - The best math channel on TH-cam... Explaining complex problems in a simple* visual and easy* to understand matter... Well ... easy and simple, if you have the will to watch them slow and repeat a lot - or if you are much smarter than me :D Much like here... ;)
@@zahoortareenIt's a brilliant Mathematics related TH-cam channel which delivers extremely detailed and informative math videos using beautiful animations. Their videos explain things in such a way that everyone from newbie to expert can understand it easily. It also helped me through my calculus course a lot! Highly recommended from me. ❤❤
I'm a software developer and although we cover the basics of how programs are using memory to execute the necessary instructions, we never went into details. This is truly the best video that I've seen and is probably the only one of its kind. Amazing work... everything that you've put into the making of this video is greatly appreciated.
I study electronics and automation with the basics of digital technology like this. Also a computer enthusiastic who overclocks as well. It is incredible to see a video on youtube this accurate and visually well made, also It helps to remind and clears some of the aspect of DRAM's. Really love this video ♥
The quality of the 3d rendering, the clarity to explain everything, as a narrator and graphically wise, and the pace is perfect. I would love to create some videos like this for architecture and construction. I really hope your channel grows to translate it into spanish. Thanks for this, is a gift to humanity. Sorry for my english, it is not my native lenguaje.
Visualizations make these complex ideas much easier to understand but I can't imagine how many hours it must have taken for your team to animate this. Absolutely amazing.
I am beyond impressed with the amount of detail and information in this video. This is some triple A content. At first, I thought over 30 minute video this better be good. At the end I was wishing it was a 90 minute video. That is how impressed I am.
The quality of the video, the simplicity when complex topics are broken down far enough and the engaging script and speaking voice make this channel a real treat!
This is an invaluable source for learning about DRAM working! University lectures don’t seem to come anywhere near this! This is extremely well illustrated and I could quickly comprehend the ideas that it was communicating. After this, I tried watching a university lecture on DRAMs and I was surprised just how hard it was to learn from a university lecture in comparison with learning through these illustrated videos. I feel this should be the way things are taught
Hats off to the engineers, researchers and inventors who made such technology possible. I can't even imagine how delicate, intricate and advanced these tech are. I sincerely appreciate the technological advancements. Much respect to brach education and team for bringing such detailed video. ❤️
RAM is one of the most complex thing to explain in a computer. I've watch dozen of videos on the subject but none of them were that detailed and clear. Your work is a true educational masterpiece
@@monad_tcp Yeah- you're right. One of the reasons why we did DRAM earlier than CPU is because it's less complex- albeit, still very complex- but definitely less complex than Cores, Pipelining, Scheduling, Caches, or really most things on the core.
One of the best youtube videos I have ever seen in my life, I have probably watched 10,000 or more hours and never seen a video more informative. You truly have my gratitude in making this art.
It's quite amazing to see there are some really smart people who understand these stuff and drastically improvement our live. Teddy, I've watched all of your video since I saw your interview with Lesics and each time I see your video I'm always in awe that no-one explains like you and your team on entire TH-cam. Looking at the efforts, dedication and amount of time that went into it makes me feel like I just can't watch this for free. So here's a very small contribution from my end. I'll be looking forward to be on patreon in near future. Keep creating such informative videos. Eagerly waiting for the GPU ones...
@@Ryanisalive Thanks for the comment. I don't think it's a question of Good or Bad but rather about sustainability. AdSense rarely pays anything satisfactory so just wanted to extend small amount on my side.
It is such a noble work to create this high quality content, reaching thousands of curious minds across the globe, and making it available for free! Thank you Branch Education and all involved in the creation of this video! You are awesome!
These videos are such a public service, explaining all this magic occurring around us - giving us appreciation for the insane tech we take for granted. Thank you!
I was looking for those explanations for years ; and nobody was able to explain the refreshing process. Thank you. This is really professional. You should receive an Oscar !
You got insane amount of respect from my side. The total thing was huge, mind blasting. Thank you tons. I was wondering that how does memory works from months. Huge applauds for you people. Keep going, Keep growing. This is the best educational video I've ever come across till now.
The way things are explained in the videos of this channel is breathtaking, the level of perfection is insane. No shortcuts are made, the animations show extreme details. I loved every aspect of this video, it's definetely worth watching the whole 35 minutes.
It is truly mind-blowing to see a 30 minute video summarize pretty much an entire semester worth of deep scientific theory after taking a course relating to the same topic. From the amazing quality of the illustrations and animations supporting the explanation to the explaining itself, this channel's videos are masterpieces and they are only getting better. Wish I found this while taking my college courses, but it serves as an amazing refresher to say the least.
It seems like my searching of learning about working of computer since my childhood at micro level of understanding has been ended after getting this video.....🙏🏻🙏🏻💥💥🌷💐 It's marvelous....I can't imagine and also very hard to believe that I have got this video on TH-cam..🙏🏻🙏🏻💥💥 Thank you a ton of very very much to you....🙏🏻🙏🏻💥💥💐🌷❤️❤️
These videos are actually insanely good. I'm absolutely fascinated by the fact people actually thought and designed all these tiny, tiny components. Figured out how they work together.
The edit is INSANE! I really respect and love for this amazing work! It's not just the 3D models are stunning the animations as well! We are lucky to have you. Total respect.
I work as a desktop support technician for a university. I've worked with and on computers since the IBM 8088. I have never been able to understand how any of the inner workings that make up these amazing systems work, until today. Thank you for this explanation of how computer main memory works. You have earned my like and subscription. Looking forward to more like this.
Namaste 🙏 Radhe Radhe 🙏 This Video lecture is incredibly detailed about how each and every thing possible in computer device with the help of DRAM and SSDs storage devices. Thank a lot for you Months and hours and hours of efforts
This must be one of the most informative and educational videos on YT and anyone should learn what's presented in the video, I consider it basic knowledge for the era we live in.
Your real-time animated videos put everybody else covering tech topics on YT to SHAME! They are simply amazing! I love the way you present so much detailed technical information in such a short time, so incredibly clearly. 👍👍
This is by far the best video about DRAM. I work with computers for over 15 years and it was super interesting to revisit some of the things in this video. Kudos for awesome job!
This is one of the best educational videos I have ever seen! The explainations were so approchable that I feel like I gained a solid understanding despite having no engineering background whatsoever! And the beautiful, realistic animations made it that much easier to understand and visuallize whats going on in my RAM sticks!
It feels like this video should be mandatory in every computer science course, especially when in the context of learning to perform proper memory management in coding, and also when learning cybersecurity... A++!
I am actually astonished at the effort it took to make this video. Super informative with very good and accurate models. Like I have no words, it's just some of the best stuff I have ever seen. You guys are amazing.
I've recently began deep diving into the architecture behind hardware in systems and this has been one of the greatest videos I've seen so far; I'm still relatively new to it all but this really helped. Thank you guys so much!

Recap by Tammy AI
Yep the Bios is loaded first which tells the CPU what channels and address all your hardware is on the motherboard a Bios is a roadmap to the Motherboard for your CPU, than it loads the boot loader and than the operating system that tells the processor the addresses to all directories and programs on your computer so the operating system is a map of the hard drive or SSD and shows your CPU the operating system your directory structure and prints it out in a easy to understand user interface for the end user you.
Thank you man I really had to go back about 10 times to understand just how fucking complex my ddr4 ram is, wow just wow it's mind blowing we as humans are capable of this
Your ability incredibly ability to explain and visualize difficult concepts is unparalleled . The amount of time to produce and edit this video must have been intense. Your videos are a gift of knowledge to humanity.
They showed sources. They cribbed sources. They...had a live human speak in a consistent tone? No expectations are given for improvements in current-gen DIMMs or future memory technologies. HBM was left out like a thing you don't see in commercial servers. You can't tune your memory timings from this video. You might want to rethink whether this video is the one that you give out SAG memberships with...
Thank you so much. I've been looking for a beginner friendly explanation of computers for so long but almost all of them seem to slip by me. Definitely wanna see more about the inner workings of the computer
Just about to finish a PhD on using DRAMs to generate unique identifiers. This is THE best illustration of a highly technical concept (let alone DRAM!) I think I have ever seen. Well done.
Dude this video is awesome. Im a VFX artist myself and i couldn't imagine if i did this how much time this would take. Simply awesome. I would love to see Behind the scenes because some parts in this video is so insane. Keep it up dude. Love these videos.
At first I was like: "Ah, just another introductory video for a non-computer person." Then, my mind was blown. Very well explained and graphically displayed.
I really love how elaborate this is and those graphics are SO smooth! It just transitions from one to the other, scenes dont actually ever change. That is super impressive. Thank you all who helped make this video and videos like these!!
these beautiful illustrations really help my monkey brain absorb so much information and even then I'm going to have to rewatch the video two or three more times to understand this otherworldly complexity of how the technology that makes the modern world go round.
Oh my goodness! Not only is this the most comprehensive description of DDR RAM on TH-cam, it's also the most well produced! Bravo! THIS is the future of education. I highly recommend sharing this video with popular tech channels like linus tech tips, gamers Nexus, etc. You will get a lot of traffic of people who are eager to learn about this topic.
This could be one of the best videos I've ever seen and I'd rate it a straight 10/10. Also, the animations helped me to get familiar with the daunting concepts of how hardwares work. Keep it up; hope that pays off as success.
I just finished my Electronic Engineering Master's degree and I can fully realize how incredible this video is. It's one of the most dense, mind-blowing video I've seen in the past few years! Good job, very clear explainations and exceptional animations ✨👌
Although my knowledge of computers is basic I absolutely loved this video and learned a lot. It is absolutely mind blowing what humans as a whole have been able to achieve. If you could go back in time and show this video to Alan Turing I could only imagine his disbelief in our advancement. Just trying to think how people came up with these things makes it all the more unbelievable. Thank you for making a great educational video.
An insane amount of technical information successfully delivered in a thorough and well thought out manner, aided by highly detailed yet easily understood animations. Truly world-class educational material that helps make the highly technical accessible to nearly everyone.
I have been wanting to better understand these concepts ever since I started building my own gaming PCs but was never able to wrap my head around it. And then in a single video it all makes sense. Amazing animations and explanations. We don't deserve content this good!
I've watched every video you guys made at least 4 times each. Just want to thank your animation team for giving my visual based learning brain the time of its life
This is the best explanation ever made. I mean, you've explained it in such a detailed and graphic way, that is incredibly awesome and clarifying at the same time. You 've won a new follower from Argentina. Thank you for your hard work and please continue doing this kind of videos !!
The information you gave in this video summarizes what a student studies for years. I can't thank you enough for your effort and hard work in bringing this information to people for free. ♥
I was working on a minecraft redstone project to create RAM. I had no prior knowledge about how real life RAM works and I am amazed at how similar my designs were. One major difference is that I didn't have capacitor drain due to using redstone comparators to read the value of a storage device, essentially a hopper.
@Branch Education You're making it possible for more people to access the feild of computer science and doing it in a simple, yet effective way. Spending an immense amount of time on planning, practicing, and executing these masterful videos is really showing in the videos themselves. Thank you from California!
Born in the late 60's, I have been fortunate enough to witness the phenomenal increase in speed (and decrease in size) of computer components, and thus be amazed by them all through my life. It saddens me that people often have little or no idea what incredible technology resides in their devices. A smartphone's SOC (system on a chip), for instance, is such an incredible feat of nano-engineering (as are many other types of chip, of course), yet people are generally oblivious to its mind-blowing wonder.

Revelation 3:20
Behold, I stand at the door, and knock: if any man hear my voice, and open the door, I will come in to him, and will sup with him, and he with me.
HEY THERE 🤗 JESUS IS CALLING YOU TODAY. Turn away from your sins, confess, forsake them and live the victorious life. God bless.
Revelation 22:12-14
And, behold, I come quickly; and my reward is with me, to give every man according as his work shall be.
I am Alpha and Omega, the beginning and the end, the first and the last.
Blessed are they that do his commandments, that they may have right to the tree of life, and may enter in through the gates into the city.
I am a CSE student your videos helps me to understand computer concept very clearly. Thanks, here is my little support for you.
Didn't expect all this information presented in just one great video. Thanks!
Really? I was surprised by how short it was, and disappointed that it didn't go into any detail...
@@Psythik It's an awesome & detailed video, with a high quality 3d models, well written script. put aside the awesome background sound effects or the ordering of information.
@@QuantumVirus Who cares about fancy animations? I much rather the uploader spend their time on providing more in-depth information, rather than wasting their energy on producing animations that add very little to the video. I need more than just surface-level knowledge.
@@Psythik Fancy animations will help people understand how it works in an easier way, allowing their brains to link the information they hear logically with the physical movements that happen in those parts. secondly, they didn't waste their energy producing animations because they already did it all good with the details. lastly, this is not a surface-level knowledge, if you can't name some of those things you did miss by watching this, i'll have to just call you a hater. you can't claim that it's surface level-knowledge without giving examples as to what are the missing things.
@@Psythik how is this surface level knowledge??
Incredibly amazing. A 30-minute video explains what teachers in my university couldn’t do in a couple of weeks.
I mean you are comparing a team of smart people, capable orators, graphic designers, and animators vs. one guy who is extremely smart and teaches for a living. Both are valuable in their own ways.
@@concernedroadratyes, indeed
It’s not so much what your teachers “can do” and more what you “can learn” in this case. The best thing a teacher could do is assign this video as homework for students like you, since it clearly demonstrates things better for you.
For me, carefully-crafted animated videos like these are a hundred (even thousand) times better and truly helpful in explaining how things work - as compared to just reading books or manuals. It's very nice to see that in this digital age, there are educators like you who are spending a considerable amount of time and effort in creating these kinds of videos. I'd be a Patreon to creators of high-quality videos like these if only I had a lot to spare. Thank you!
It Mano technology
Videos like this make me appreciate technology even more.
Thank you for answering my questions with your easy to understand yet detailed videos!
respect for the donation bro
Good 👍😊
I must say, I'm truly impressed! Your 3D teaching video on DRAM is absolutely phenomenal. It's rare to find such a clear, engaging, and technically sound explanation of a complex topic. Your creativity in using 3D visualization truly elevates the learning experience and makes understanding DRAM much more accessible. Thank you for sharing your knowledge in such an eloquent and impactful way!
Amazing! The clearest video about computer devices that I have ever seen. I believe it is more propriate to watch the videos slowly so that the understanding can be comprehensive. Maybe a possible way is to separate one long videos in to several independent ones.
Incredible. The animation and voice acting are of insane quality. Thank you for your hard work 🙏
Too many "swoosh" annoying distracting and stressful sound effects, didn't finish. Please stop doing that.
This is amazing visualization of how DRAM works. When I studied microelectronics, it took about 3 hour long lecture to professor to explain just basic concepts. This explains a lot of details that are normally neglected, and it takes only 30 minutes. Only one think that was neglected about SSDs, that data are read/written there in pages, because it makes more sense to load/save whole data array at once, while when data are processed individual bit/byte/word operations are common.
Well, we have a separate series of 4 videos that cover just SSDs, that total ~45m duration.
Schools should incorporate this channel's videos into the curriculum.
Thanks for cramming a couple of university courses worth of information into a 35 minute video! I had to watch it in 4 stages, but in the end it's a lot more effective than many lecturers! I can't even begin to imagine how hard it must have been to not only understand it all to a point when you can explain this to others, but to also accurately animate all of this.
I learned so much from you in the past 3 years that it feels really illegal to continue to watch such gold content for free - so here is my first "super thanks" ever - you deserve a lot more than this!
I will look for sure to soon become a patreon member of this channel, 3Blue1Brown and only a few more - but this 2 channels with highest priority... and I am not even an engineer or working in similar field!
Glad to see that you will very soon meet the 1M subscribers finally! Looking forward to the next video, whatever it will be! :)

@@zahoortareen www.youtube.com/@3blue1brown - The best math channel on TH-cam... Explaining complex problems in a simple* visual and easy* to understand matter... Well ... easy and simple, if you have the will to watch them slow and repeat a lot - or if you are much smarter than me :D
Much like here... ;)
@@zahoortareenIt's a brilliant Mathematics related TH-cam channel which delivers extremely detailed and informative math videos using beautiful animations. Their videos explain things in such a way that everyone from newbie to expert can understand it easily. It also helped me through my calculus course a lot! Highly recommended from me. ❤❤
I'm a software developer and although we cover the basics of how programs are using memory to execute the necessary instructions, we never went into details. This is truly the best video that I've seen and is probably the only one of its kind. Amazing work... everything that you've put into the making of this video is greatly appreciated.
Yes the details is just insane 🎉
Of all the videos I've watched on how Dram works, this is by far the most detailed
I study electronics and automation with the basics of digital technology like this. Also a computer enthusiastic who overclocks as well. It is incredible to see a video on youtube this accurate and visually well made, also It helps to remind and clears some of the aspect of DRAM's. Really love this video ♥
The quality of the 3d rendering, the clarity to explain everything, as a narrator and graphically wise, and the pace is perfect.
I would love to create some videos like this for architecture and construction.
I really hope your channel grows to translate it into spanish.
Thanks for this, is a gift to humanity.
Sorry for my english, it is not my native lenguaje.
Also,

@@gerarbendfeldt a bit... ;)
One of those videos which you'll watch a lot of times. The amount of work that went into this! Really appreciate the efforts by the team!
Glad you enjoyed it!
@@BranchEducationglad you're glad he enjoyed it ❤️
Visualizations make these complex ideas much easier to understand but I can't imagine how many hours it must have taken for your team to animate this. Absolutely amazing.
This is the most incredible in depth video on RAM I’ve ever seen. The amount of detail, description, & 3D modeling is mind blowing. Well done Branch.
I'm only 6 minutes in and it is already clear that this video is INSANE. It can't get better than this. Incredible work!
This is very informative with excellent visualization and simplification of the complex technologies presented. Thanks for making these videos!
Thank you so much!! We 5/5 stars appreciate it!
I'm kind of amazed that all of this complexity works so smoothly, day in and day out across millions of machines.
I am beyond impressed with the amount of detail and information in this video. This is some triple A content. At first, I thought over 30 minute video this better be good. At the end I was wishing it was a 90 minute video. That is how impressed I am.
The background music 🎶 makes it better
The quality of the video, the simplicity when complex topics are broken down far enough and the engaging script and speaking voice make this channel a real treat!
This is an invaluable source for learning about DRAM working! University lectures don’t seem to come anywhere near this! This is extremely well illustrated and I could quickly comprehend the ideas that it was communicating. After this, I tried watching a university lecture on DRAMs and I was surprised just how hard it was to learn from a university lecture in comparison with learning through these illustrated videos. I feel this should be the way things are taught
Hats off to the engineers, researchers and inventors who made such technology possible. I can't even imagine how delicate, intricate and advanced these tech are. I sincerely appreciate the technological advancements.
Much respect to brach education and team for bringing such detailed video. ❤️
RAM is one of the most complex thing to explain in a computer. I've watch dozen of videos on the subject but none of them were that detailed and clear. Your work is a true educational masterpiece
I'm afraid it's not. CPU is the most complex device on a computer. RAM is one of the most simple and straight forward things to explain.
Cache locking and invalidation is the most complex thing. RAM is pretty simple and straight-forward near other things.
@@monad_tcp Yeah- you're right. One of the reasons why we did DRAM earlier than CPU is because it's less complex- albeit, still very complex- but definitely less complex than Cores, Pipelining, Scheduling, Caches, or really most things on the core.
@@speggeri90 Hey, people have to implement compute-in-memory somehow. HBM can't have all the glory.
Thanks! Keep up the amazing work! Your work is loved by many!
Thanks supporting so we can get more amazing free content!
One of the best youtube videos I have ever seen in my life, I have probably watched 10,000 or more hours and never seen a video more informative. You truly have my gratitude in making this art.
I can't even imagine the amount of time it took to made this video with all these amazing incredibly detailed 3d renders. Great work!
Thanks!!
This channel has many masterpiece videos.
It's quite amazing to see there are some really smart people who understand these stuff and drastically improvement our live.
Teddy, I've watched all of your video since I saw your interview with Lesics and each time I see your video I'm always in awe that no-one explains like you and your team on entire TH-cam.
Looking at the efforts, dedication and amount of time that went into it makes me feel like I just can't watch this for free. So here's a very small contribution from my end. I'll be looking forward to be on patreon in near future.
Keep creating such informative videos. Eagerly waiting for the GPU ones...
I am surprised that good people like you still exist on this planet!
@@Ryanisalive Thanks for the comment. I don't think it's a question of Good or Bad but rather about sustainability. AdSense rarely pays anything satisfactory so just wanted to extend small amount on my side.
Thanks for keeping this free for the rest of us 👍🐐
Rahul, thanks for supporting the channel so we can get more amazing content for free!
The video is very very interesting
It is such a noble work to create this high quality content, reaching thousands of curious minds across the globe, and making it available for free! Thank you Branch Education and all involved in the creation of this video! You are awesome!
This is lowkey one of the best channels I've ever stambled across
This is such a beautiful presentation, and the analogs to how it affects the performance and logistics of video games really hits the point home.
These videos are such a public service, explaining all this magic occurring around us - giving us appreciation for the insane tech we take for granted. Thank you!
I was looking for those explanations for years ; and nobody was able to explain the refreshing process.
Thank you. This is really professional. You should receive an Oscar !
You got insane amount of respect from my side. The total thing was huge, mind blasting. Thank you tons. I was wondering that how does memory works from months. Huge applauds for you people. Keep going, Keep growing. This is the best educational video I've ever come across till now.
The way things are explained in the videos of this channel is breathtaking, the level of perfection is insane. No shortcuts are made, the animations show extreme details. I loved every aspect of this video, it's definetely worth watching the whole 35 minutes.
It is truly mind-blowing to see a 30 minute video summarize pretty much an entire semester worth of deep scientific theory after taking a course relating to the same topic. From the amazing quality of the illustrations and animations supporting the explanation to the explaining itself, this channel's videos are masterpieces and they are only getting better. Wish I found this while taking my college courses, but it serves as an amazing refresher to say the least.
wasn't really deep or scientific then but I can see what you mean
You all have inspired me to the deepest Level. I'm in awe. Thank you for the golden education!!!
It seems like my searching of learning about working of computer since my childhood at micro level of understanding has been ended after getting this video.....🙏🏻🙏🏻💥💥🌷💐
It's marvelous....I can't imagine and also very hard to believe that I have got this video on TH-cam..🙏🏻🙏🏻💥💥
Thank you a ton of very very much to you....🙏🏻🙏🏻💥💥💐🌷❤️❤️
The quality and explanations are amazing keep up the good work
Information-rich, optimally-ordered breakdown. Breathtaking presentation.
This channel is a GEM. Thanks for what you do!
For the first time in my life, I completely watched the promotion part of a TH-cam video😅
That's how good you guys are...
These videos are actually insanely good. I'm absolutely fascinated by the fact people actually thought and designed all these tiny, tiny components. Figured out how they work together.
The edit is INSANE! I really respect and love for this amazing work!
It's not just the 3D models are stunning the animations as well!
We are lucky to have you. Total respect.
When video says "watch me at 1.25 speed first time and at 1.5 right after" you just admit it's a diamond grade content.
I work as a desktop support technician for a university. I've worked with and on computers since the IBM 8088. I have never been able to understand how any of the inner workings that make up these amazing systems work, until today. Thank you for this explanation of how computer main memory works. You have earned my like and subscription. Looking forward to more like this.
Namaste 🙏
Radhe Radhe 🙏
This Video lecture is incredibly detailed about how each and every thing possible in computer device with the help of DRAM and SSDs storage devices.
Thank a lot for you Months and hours and hours of efforts
This must be one of the most informative and educational videos on YT and anyone should learn what's presented in the video, I consider it basic knowledge for the era we live in.
Best anims, interesting topics, most detailed, simply explained videos with nice voice! TOP of the TOP💥
Your real-time animated videos put everybody else covering tech topics on YT to SHAME! They are simply amazing! I love the way you present so much detailed technical information in such a short time, so incredibly clearly. 👍👍
Keep teaching us about high-technology, and I will keep supporting you in return.
This is by far the best video about DRAM. I work with computers for over 15 years and it was super interesting to revisit some of the things in this video. Kudos for awesome job!
This is one of the best educational videos I have ever seen! The explainations were so approchable that I feel like I gained a solid understanding despite having no engineering background whatsoever! And the beautiful, realistic animations made it that much easier to understand and visuallize whats going on in my RAM sticks!
Thanks!! This is exactly what we were going for, and I'm glad we hit the mark.
I have been working on HBM for 3 years now and this video made my concepts more clear!! Much respect to you guys for making these!!
It feels like this video should be mandatory in every computer science course, especially when in the context of learning to perform proper memory management in coding, and also when learning cybersecurity... A++!
Great video! This will be extremely valuable to engineering students
Very like your channel too
You also create awesome videos. In fact, I with my gf watched your titanic video yesterday.
I am actually astonished at the effort it took to make this video. Super informative with very good and accurate models. Like I have no words, it's just some of the best stuff I have ever seen. You guys are amazing.
I've recently began deep diving into the architecture behind hardware in systems and this has been one of the greatest videos I've seen so far; I'm still relatively new to it all but this really helped. Thank you guys so much!

Recap by Tammy AI
Excellent recap!!
Yep the Bios is loaded first which tells the CPU what channels and address all your hardware is on the motherboard a Bios is a roadmap to the Motherboard for your CPU, than it loads the boot loader and than the operating system that tells the processor the addresses to all directories and programs on your computer so the operating system is a map of the hard drive or SSD and shows your CPU the operating system your directory structure and prints it out in a easy to understand user interface for the end user you.
This should be part of the video's description.
Thank you man I really had to go back about 10 times to understand just how fucking complex my ddr4 ram is, wow just wow it's mind blowing we as humans are capable of this
Your ability incredibly ability to explain and visualize difficult concepts is unparalleled . The amount of time to produce and edit this video must have been intense. Your videos are a gift of knowledge to humanity.
They showed sources. They cribbed sources. They...had a live human speak in a consistent tone? No expectations are given for improvements in current-gen DIMMs or future memory technologies. HBM was left out like a thing you don't see in commercial servers. You can't tune your memory timings from this video. You might want to rethink whether this video is the one that you give out SAG memberships with...
Thank you so much. I've been looking for a beginner friendly explanation of computers for so long but almost all of them seem to slip by me. Definitely wanna see more about the inner workings of the computer
These videos are a gold standard of how to teach a complex topic.
Just about to finish a PhD on using DRAMs to generate unique identifiers. This is THE best illustration of a highly technical concept (let alone DRAM!) I think I have ever seen. Well done.
Dude this video is awesome. Im a VFX artist myself and i couldn't imagine if i did this how much time this would take. Simply awesome. I would love to see Behind the scenes because some parts in this video is so insane. Keep it up dude. Love these videos.

At first I was like: "Ah, just another introductory video for a non-computer person." Then, my mind was blown. Very well explained and graphically displayed.
I was in the same boat. I clicked on the video thinking, "I'll humor you TH-cam. I might learn *something* new from this." I ended up learning a lot.
Explaining Computer engineering with such class. Back in the days you had to pay to watch a show even half of this quality.
I really love how elaborate this is and those graphics are SO smooth! It just transitions from one to the other, scenes dont actually ever change. That is super impressive. Thank you all who helped make this video and videos like these!!
these beautiful illustrations really help my monkey brain absorb so much information and even then I'm going to have to rewatch the video two or three more times to understand this otherworldly complexity of how the technology that makes the modern world go round.
Oh my goodness! Not only is this the most comprehensive description of DDR RAM on TH-cam, it's also the most well produced! Bravo! THIS is the future of education. I highly recommend sharing this video with popular tech channels like linus tech tips, gamers Nexus, etc. You will get a lot of traffic of people who are eager to learn about this topic.
This could be one of the best videos I've ever seen and I'd rate it a straight 10/10. Also, the animations helped me to get familiar with the daunting concepts of how hardwares work. Keep it up; hope that pays off as success.
It is unbelievable content of such quality is available to this generation free of cost
I just finished my Electronic Engineering Master's degree and I can fully realize how incredible this video is. It's one of the most dense, mind-blowing video I've seen in the past few years!
Good job, very clear explainations and exceptional animations ✨👌
An incredibly beautiful, well made video! The visuals make this so easy to follow along!
The amount of work put intro this video is insane. I didn't saw a documentary about computers which looked this good. Awesome job.
I feel so fortunate to have your videos so readily available!
this is the most impressive display of ram I've ever seen and the fluidity and small important details even taught me a lot.
I really admire the way you explained it in such detail.I love this video so much
Although my knowledge of computers is basic I absolutely loved this video and learned a lot. It is absolutely mind blowing what humans as a whole have been able to achieve. If you could go back in time and show this video to Alan Turing I could only imagine his disbelief in our advancement. Just trying to think how people came up with these things makes it all the more unbelievable. Thank you for making a great educational video.
An insane amount of technical information successfully delivered in a thorough and well thought out manner, aided by highly detailed yet easily understood animations. Truly world-class educational material that helps make the highly technical accessible to nearly everyone.
I have been wanting to better understand these concepts ever since I started building my own gaming PCs but was never able to wrap my head around it. And then in a single video it all makes sense. Amazing animations and explanations. We don't deserve content this good!
I can't believe the production quality of this video, and I'm not even six minutes in. This is amazing.
Thanks you so much!
I usually don't comment on TH-cam!
But your effort + the level of the animation ❤️❤️
Never seen such a mesmerising animation!
I've watched every video you guys made at least 4 times each. Just want to thank your animation team for giving my visual based learning brain the time of its life
This is the best explanation ever made. I mean, you've explained it in such a detailed and graphic way, that is incredibly awesome and clarifying at the same time. You 've won a new follower from Argentina. Thank you for your hard work and please continue doing this kind of videos !!
The information you gave in this video summarizes what a student studies for years. I can't thank you enough for your effort and hard work in bringing this information to people for free. ♥
Loved when these type of videos were played in class growing up. Was never on this level though. The work these guys do is phenomenal.
I was working on a minecraft redstone project to create RAM. I had no prior knowledge about how real life RAM works and I am amazed at how similar my designs were. One major difference is that I didn't have capacitor drain due to using redstone comparators to read the value of a storage device, essentially a hopper.
@Branch Education You're making it possible for more people to access the feild of computer science and doing it in a simple, yet effective way. Spending an immense amount of time on planning, practicing, and executing these masterful videos is really showing in the videos themselves. Thank you from California!

Born in the late 60's, I have been fortunate enough to witness the phenomenal increase in speed (and decrease in size) of computer components, and thus be amazed by them all through my life.
It saddens me that people often have little or no idea what incredible technology resides in their devices. A smartphone's SOC (system on a chip), for instance, is such an incredible feat of nano-engineering (as are many other types of chip, of course), yet people are generally oblivious to its mind-blowing wonder.
