That can't be right. I learned this along with much more detail some 40 years ago. They were called books, we carried them and had to read/study them. The professor played the role of the video with blackboard showing the concepts. And we were required to write a low level program to read/write data on disks as part of the class.

I really feel that this video was one of the most enjoyable ones I've ever watched in multiple years of using youtube. It was clear and explained things in an easy-to-understand way that I found extremely easy to understand, and I really found my mind blown away by the sheer scale of this technology (especially in the final chapters).

Edit: I've just rewatched the video again with the comments, and I feel kind of sad knowing that I won't be able to find many other videos out there that will give me as much of a enjoyable and wholesome experience to this one. I wish I could just magically erase this memory from my brain (maybe with 40v like they use to erase the blocks? lol) just to watch it again for the "first" time (and then again with the comments lol) also I'm starting to wish I went for a higher donation tier, 2 pounds is starting to seem quite stingy for such an amazing learning experience I hope comments like mine reach Teddy (the founder of this channel) so that people like me can let him know how much we appreciate their videos.

This didn't just happen over night, it was a long process to get to where we are and took many great minds. It would be cool to see a documentary more into the history and evolution of this stuff. It's cool to see old physical records people used to listen to music on and the old cameras they used to take pictures physically vs digitally. I'm amazed by the online multi-player video games and virtual reality stuff blows my mind, that's what made me curious about how hard drives and the ssd work and are used. Theres so much to learn, it's hard to wrap my head around. And it all happened in a relatively short time compared to how long we've been on this earth. We have these big brains and eyes gotta use them for something.
I have always wondered what happended or what has been discovered that technology started to grow potentially in just a few decades... I mean, how engineers were able to progress so far and fast in just a couple of dacades than in 1 thousand years ?
@@martinlarrosa08 I love that it's just a bunch of nerds that just REALLY wanted to math as hard as possible. It started with the obsessive need to calculate.

Very good production value and the information is given at a level which is both accessible to those with little to no understanding of technology while still being informative to those who are technical but have no experience with this particular technology. Massive kudos!
@@thepiyushsharrma I will. I think I'll explore communication satellites and the engineering of how a satellite phone on earth can communicate with something in space. First I gotta finish a few episodes more on SSDs/ VNAND
This is SO incredible. I consider myself a tech enthusiast, and knew that it was very complex, but it's truly shocking how intelligent people are; the designers of SSDs, and their predecessors, are unbelievably brilliant.
It really puts into perspective how far behind the rest of humanity is we all thrive off of a technolgy that only a hand full of humans can even build from scratch. Like monkeys that enjoy macaroni and cheese but have no idea how to make it them selves.
That is also exactly how televisions work, or some "holographic" cubes work. And it is based on how every computer has been working these last 40 years or so
I have 10+ years of experience working with SSD firmwares, but hadn't understood SSD internals so better in such a short time. Thank you for this informative video !!!
Thanks!! I appreciate it. It is indeed growing incredibly fast. It’s just insane how quickly companies can turn around new designs of SoCs and other microchips.
I'm an engineering student Finally you're the only person who given me the answer of this mystery . You have worked hard for spreading your knowledge. I'll tell my friends to subscribe your channel
An additional thing to this video is I read an article about SSD drives that said the controller also keep track of how many times a cell has been used because the number of times a cell can be used is limited compared to traditional hard drives. The controller actually locates the least used cells in memory and that's where it saves information, in other words a file could be all over the place bit by bit instead of stored sequentially.
The controller in a HDD does similar things. Your data in the HDD isn't stored sequentially in most cases as well. But sequentially writes (and reads) are faster and therefore preferred when possible.
@@JustSomeGuy009 Yes, correct, so back in the days we used these programs that would rearrange the files they are stored sequentially because with a mechanical read/write head it improved the speed of reading files and also prolonged the life of the drive.
@@JustSomeGuy009 It's really not the same thing at all. For solid state memory, getting blocks in order that way is not especially important, but what is important is not writing to the same cell too many cells over the course of its life. Wear leveling is the usual name, and it's important.
I graduated from engineering university but I did never fully understand how these memory cells work . Watching your video for 18 min enlightenmented my whole life
There's a surprising amount of art related skills. Designing PCBs are pretty much a massive multi layer connect the dots, I've done it, and made little pictographs in the corner of my PCBs for fun.
There's no "perfect" way of speaking. Pronunciation varies and language evolves over time due to this. This is the first thing you learn in linguistics. There is no "right" or "wrong" way to pronounce words, within reason. Spelling, on the other hand, has no variability.
I like how you demonstrate the basics of electronics "building blocks" and "duplication". Many circuits follow this standard recipe; create a circuit and duplicate it. Good job getting all of the information across in a fun visual. Funny how far we have come from the simple D-latch memory.
I usually don't write comments. But man, your explaining is so concise and clear, that I can follow along seamlessly. The solid state drive technology is absolutely mind-blowing and so incredibly fast.
Technology is a very broad concept. The technologies existed. CMOS was invented in the 1960s. Nand Flash memory is a direct development of EPROM. And so on. Basic manufacturing principles also remains pretty much the same. (One example of this continuity: Large parts of the industry switched from metal gates to self aligned gates made out of polycrystalline silicon in the late 1960s, but went back again to metals (cu or al) around year 2000, for better performance in CPUs.) But, sure, the "constant" shrinking (until now!) of transistors has made manufacturing and processing techniques much more elaborate and expensive since 1978.
You guys didn't experienced on your time but take note all improvements currently are just and ideas in your time, and still they are using bit. in short they can't skip inventing from 1970's directly to 2020
You are not alone mate, I designed a product that first used 1K memory, it was soon replaced by a 4K static ram, then they stopped making those as technology moved on so fast, I had to change my pcb layout to accomodate bigger chip , then that became obsolete and had to use a 16K chip with 15K going to waste, only 1 K being used, so these have become obsolete now for quite some time, over a decade ago, but you can still buy some old stock, so now no one bothers with 128K, or 256K and all of these are now becoming defunct replaced with serial memories, of mega and giga bits!
@@mgabrielle2343 Hmm... Perhaps in the 1970s. But things have been pretty stable since the mid 1980s. You can still buy static RAMs as small as 8Kx8 (i.e. brand new, no old stock). The ubiquitous 32Kx8 SRAM (62c256 an similar) are still considered a standard component, with several different manufacturers over the world.
This is the first time I appreciate the multiple ads in a video, it helped my brain to catch up what's been said. Superb narration! Didn't realize 17min has passed so quickly. 👍
I bought a 4TB external SSD that fits in my hand so I was curious how it's possible and how it works.. It's insane how the tech world has made it possible to store so much data it such a small place..
Same here. Yes, it's like magic what these smart people create! Kudos. I hold it in my hand, and knowing that 2 complete Movie Projects are stored there. Despite the bad times, what a wonderful time to be alive.
Thanks!! I don't search for conspiracy theories, or care much for them- but I bet there's one that says microchip technology was given to us by aliens.
@@Nikkk6969 I mean it's extremely difficult to reverse engineer modern SOCs. I don't see how anyone could reverse engineer a chip likely more complex than the ones we have today. The Field Effect Transistor was proposed in 1926 and there was a long history of research into electricity before that. en.wikipedia.org/wiki/Transistor And if a probe crashed on Earth that would mean a lot more should be finding us because of how large space is and how far apart planets are. There would need to be many populated planets out there sending out probes in many directions. It will take Voyager millenia before it finds a planet.
Understanding how this kind of stuff works while watching it on my phone made me lock the screen and literally just stare at it and imagine how incredible it is that there is this much technology in such a tiny device
And for that work, you (people) pay their wages so they van afford their life plus a meal at McDonald's. So no complain and no regrets, you paid for your memes.
@@chaoticmasterpiece That old Moores law does not really hold anymore. Physical limits in scaling are reached for most kinds of chips. But NAND Flash (used in SSD) are built in multiple layers. So that's why they can continue to develop without even shrinking the transistors any more. Processors get far to hot for that method. Many other types of chips do as well.
Awesome video! I am a VLSI engineer who worked on LPDDR3/LPDDR4 and memory controllers myself, I can say this is really a great way to introduce a memory chip !😄
Am a Mechanical engineering final year student, I wondered how it works since my 10th standard... It's a superb video, the graphic design explain the content in such that each and everyone could understand it very easily. Loved it. Thankyou
This is the kind of video that made youtube what it is today but sadly these are no longer promoted by youtube as well as it should be. Kudos to the awesome team for making this !
This is an amazing visual explanation. I worked in flash-based data recovery for 2 years. I was familiar with the logical structures and relative sizes of pages, blocks and banks (the 8 stacks of chips inside the physical package), but I could never visualise them physically before watching this video. At least not the internal structure of the blocks. I have seen many X-rays of VNAND, and your depiction of the 8 staggered banks top of each other, with the rows of copper wire bonds between them was 100% accurate. I think I’d love to see your take on how flash controllers work, how they translate coherent binary from say an ascii text file, to the heavily obscured mess that actually gets written to the NAND. If your file is made up of the binary ‘1010 1010’, that is not the sequence that gets stored physically, Contiguous logical data like that ‘1010 1010’ sequence will first get split up and scrambled with a XOR pattern, than turns it in to effectively ‘random’ data. It then gets split across different pages, belonging to different blocks on different banks. This is called the “flash translation layer”, effectively the layer of logic that converts logical data storage to physical data storage. All this is done so that any given file is stored in as many separate pages as possible. You can only access one page per block at a time, so it would be slow to have to wait for every page to be read sequentially if your whole file is stored in one block. Instead, if you split a single file across many blocks and many banks, you can read multiple pages of that file simultaneously, speeding up the read and write processes. This method of parallelising data access is why solid state drives have become so fast. Instead of having one person read a 100-page book page-by-page, you split the book up in to 100 separate pages, and have 100 people read a page simultaneously. Once they’ve each read a page, it’s quicker to rearrange them in to the order of the pages they read, than it would have been to wait for one person to read all 100 pages.
I never said that on youtube in my entire life except when I discovered your channel but: I feel terribly thankful to be born at that time to have the chance to access such quality educational content for free and honestly realizing that at the end of your video made me sincerly feel emotional and I had tears from such wholesomeness. And believe me, getting emotional for something like this rarely happened in my life. Sincerely, Thank you for you time, work, dedication, ability to explain. These 17 minutes felt like 3.
I absolutely loved the creators comments, given extra important information while adding insight of how much work went into this video. Gives a greater perspective on how much work good teaching methods actually take
As an nand flash controller engineer, this is the most clearly video description about nand flash’s structure I’ve ever seen ... that’s an amazing job! Thanks for sharing.
Wow, this really is amazing. The incredible small sizes of technology - if there weren‘t people like you describing it, it all would be like obscure magic.
it's still obscure magic. how can the charge trap be read? like how does it receive the signal to send the message of how many charges it holds? fascinating
Yea its one of the many things we use everyday that are JFM( Just F**king Magic) But yea how they are able to read each cell and how precise is that voltage per cell would be cool to know also what material or element are they made of? Its like most things in tech we have now in that its a voodoo black magic onion and there's always a more incredible thing as you go deeper into the next layer.
Defense world is essentially decades way ahead of the civilization is told! It's scary but awesomeness too. I also love the fact I will never decide to be on the wrong recieving end of the USA 🇺🇸!
i am a tech enthusiast and just started a channel about technology and gadgets so i wanted to learn more about gadgets technology to help more people and gain knowledge and found your video now i feel like i know only 10% .... so much to learn about. ty
Back in 1988 I was working as a contractor to Intel and was approached by an engineer looking at a problem they had to address cache memory. On a napkin I had with my lunch one day I scribbled out something similar to this design (but very simplified). It appears that my concept was accepted and multiplied a few million times. Glad I was able to help.
Everyone take a second and imagine how insanely large the .blend file for this video must be. Now imagine all the memory cells that contain the data. Imagine how crazily advanced it is that some electrons zooming through metal on a PCB are able to be processed by a CPU, GPU, and an SSD for storage. Then they get sent to a screen on your phone and give you an animation like this. My brain is thinking of all the tiny pieces that go into it and above all I just wonder how the heck it got like this. Amazing video, a gem of TH-cam.
One of very rare videos, that are not afraid of being technical. I loved it, especially comments through subtitles, adds some replaybility and also had me know more about the content. I hope I can learn more here. Being a CS student who like computer systems, and hence love to interact with lower layers, I find this very insightful
What I find the most mindblowing isn't so much the concept of memory, but the feat of manufacturing these complex structures. I mean, a flash trap has to be the size of what... a fraction of a micron? How do you make something that small, that also has a functon?
When did you see 12MPx picture taking up hundreds of megabits of memory? Raw from my 14MPx camera is about 12 megabytes (x8 is roughly 100 megabits and even raw often uses some sort of lossless compression algorithm). This calculated size of the picture is stored only in ram.
Using photolithography, layer by layer with harsh strange chemicals & very expensive highly specialized tools in building that cost billions with high operating costs that run 24/7
Very very pure water & clean stable electricity are two of the key ingredients + acids & precision polymers & robots & automation of the most precise type for high volume high throughput // to make billions of chips
Yeah! I was an engineer for a long time, and I always felt I did so little- I would design just a number of cable harnesses and mechanisms, and it would take me half a year to a year to fully finalize it.
Sure, but you cannot beat the cost + memory density. Hard drive can hold as much as 14-20TB (Enterprise version) Like $700 each. But for 8TB takes like $2000. Cost will reduce in the next 5-10 years
Bravo! You take the art of teaching to new heights. Most people can not imagine how many hours of hard work has gone into producing this 17 minutes of extremely information dense educational video. I for one would appreciate if at the end of the video you would add how long it took you to produce this amazing educational content. It is easy to take your work for granted just as it is easy to take the work of those amazing engineers for granted. Thank you sit! I hope the rest of us prove to be worthy of your amazing efforts!
Here I am watching this video a second time on another browser, just to be able to upvote it. I use computers since the 80s but never really thought about how flash memory works and just took it as a given tech´. This video does a good job explaining the technology behind it on a basic level so anyone can understand it. Great job on the visualisation!

This didn't just happen over night, it was a long process to get to where we are and took many great minds. It would be cool to see a documentary more into the history and evolution of this stuff. It's cool to see old physical records people used to listen to music on and the old cameras they used to take pictures physically vs digitally.

Hey bro keep this enthusiasm up, you could be teaching other Americans cramming before finals about this.
This is SO incredible. I consider myself a tech enthusiast, and knew that it was very complex, but it's truly shocking how intelligent people are; the designers of SSDs, and their predecessors, are unbelievably brilliant.
It really puts into perspective how far behind the rest of humanity is we all thrive off of a technolgy that only a hand full of humans can even build from scratch. Like monkeys that enjoy macaroni and cheese but have no idea how to make it them selves.
That is also exactly how televisions work, or some "holographic" cubes work. And it is based on how every computer has been working these last 40 years or so
Well this is just covering V- NAND memory there's different types out there that work a bit differently but same general concept
in a matter of years, someone is going to replicate a human mind with the ssd concept.
I'm sure there is something they don't tell us.

An additional thing to this video is I read an article about SSD drives that said the controller also keep track of how many times a cell has been used because the number of times a cell can be used is limited compared to traditional hard drives. The controller actually locates the least used cells in memory and that's where it saves information, in other words a file could be all over the place bit by bit instead of stored sequentially.
If every bit of complexity is written down and documented, which I'm sure it is, the resulting amount paper would probably crush me if I got under it
The controller in a HDD does similar things. Your data in the HDD isn't stored sequentially in most cases as well. But sequentially writes (and reads) are faster and therefore preferred when possible.
@@JustSomeGuy009 Yes, correct, so back in the days we used these programs that would rearrange the files they are stored sequentially because with a mechanical read/write head it improved the speed of reading files and also prolonged the life of the drive.
Yes. This is commonly called wear leveling, and it's very important for flash memory cells.
@@JustSomeGuy009 It's really not the same thing at all. For solid state memory, getting blocks in order that way is not especially important, but what is important is not writing to the same cell too many cells over the course of its life. Wear leveling is the usual name, and it's important.
I graduated from engineering university but I did never fully understand how these memory cells work . Watching your video for 18 min enlightenmented my whole life

I like how you demonstrate the basics of electronics "building blocks" and "duplication". Many circuits follow this standard recipe; create a circuit and duplicate it. Good job getting all of the information across in a fun visual. Funny how far we have come from the simple D-latch memory.
I usually don't write comments. But man, your explaining is so concise and clear, that I can follow along seamlessly. The solid state drive technology is absolutely mind-blowing and so incredibly fast.
Bravo! As a retired electronics tech, I appreciate discovering these technologies that did not exist when I was studying electronics in 1978!!!
Technology is a very broad concept. The technologies existed. CMOS was invented in the 1960s. Nand Flash memory is a direct development of EPROM. And so on. Basic manufacturing principles also remains pretty much the same. (One example of this continuity: Large parts of the industry switched from metal gates to self aligned gates made out of polycrystalline silicon in the late 1960s, but went back again to metals (cu or al) around year 2000, for better performance in CPUs.) But, sure, the "constant" shrinking (until now!) of transistors has made manufacturing and processing techniques much more elaborate and expensive since 1978.
You guys didn't experienced on your time but take note all improvements currently are just and ideas in your time, and still they are using bit.
in short they can't skip inventing from 1970's directly to 2020
You are not alone mate, I designed a product that first used 1K memory, it was soon replaced by a 4K static ram, then they stopped making those as technology moved on so fast, I had to change my pcb layout to accomodate bigger chip , then that became obsolete and had to use a 16K chip with 15K going to waste, only 1 K being used, so these have become obsolete now for quite some time, over a decade ago, but you can still buy some old stock, so now no one bothers with 128K, or 256K and all of these are now becoming defunct replaced with serial memories, of mega and giga bits!
@@mgabrielle2343 Hmm... Perhaps in the 1970s. But things have been pretty stable since the mid 1980s. You can still buy static RAMs as small as 8Kx8 (i.e. brand new, no old stock). The ubiquitous 32Kx8 SRAM (62c256 an similar) are still considered a standard component, with several different manufacturers over the world.
This is the first time I appreciate the multiple ads in a video, it helped my brain to catch up what's been said. Superb narration! Didn't realize 17min has passed so quickly. 👍
I bought a 4TB external SSD that fits in my hand so I was curious how it's possible and how it works.. It's insane how the tech world has made it possible to store so much data it such a small place..

Love your little disclaimer: "No aliens were involved in the development of this technology."
Thanks!! I don't search for conspiracy theories, or care much for them- but I bet there's one that says microchip technology was given to us by aliens.
@Magister700, @Branch Education: I wouldn’t be the slightest surprised if most of this technology was recovered from aliens.
@@Nikkk6969 I mean it's extremely difficult to reverse engineer modern SOCs. I don't see how anyone could reverse engineer a chip likely more complex than the ones we have today.
The Field Effect Transistor was proposed in 1926 and there was a long history of research into electricity before that.

And if a probe crashed on Earth that would mean a lot more should be finding us because of how large space is and how far apart planets are. There would need to be many populated planets out there sending out probes in many directions.

@@jimmyzhao2673 then how come all my alien friends only have 3 fingers?
How do they make stuff this small btw
This is an amazing visual explanation.
I worked in flash-based data recovery for 2 years. I was familiar with the logical structures and relative sizes of pages, blocks and banks (the 8 stacks of chips inside the physical package), but I could never visualise them physically before watching this video. At least not the internal structure of the blocks.
I have seen many X-rays of VNAND, and your depiction of the 8 staggered banks top of each other, with the rows of copper wire bonds between them was 100% accurate.
I think I’d love to see your take on how flash controllers work, how they translate coherent binary from say an ascii text file, to the heavily obscured mess that actually gets written to the NAND.
If your file is made up of the binary ‘1010 1010’, that is not the sequence that gets stored physically,
Contiguous logical data like that ‘1010 1010’ sequence will first get split up and scrambled with a XOR pattern, than turns it in to effectively ‘random’ data.
It then gets split across different pages, belonging to different blocks on different banks.
This is called the “flash translation layer”, effectively the layer of logic that converts logical data storage to physical data storage.
All this is done so that any given file is stored in as many separate pages as possible. You can only access one page per block at a time, so it would be slow to have to wait for every page to be read sequentially if your whole file is stored in one block.
Instead, if you split a single file across many blocks and many banks, you can read multiple pages of that file simultaneously, speeding up the read and write processes.
This method of parallelising data access is why solid state drives have become so fast.
Instead of having one person read a 100-page book page-by-page, you split the book up in to 100 separate pages, and have 100 people read a page simultaneously.
Once they’ve each read a page, it’s quicker to rearrange them in to the order of the pages they read, than it would have been to wait for one person to read all 100 pages.
Wow, your comment made me a bit more intelligent 🙏🏼😂

Back in 1988 I was working as a contractor to Intel and was approached by an engineer looking at a problem they had to address cache memory. On a napkin I had with my lunch one day I scribbled out something similar to this design (but very simplified). It appears that my concept was accepted and multiplied a few million times. Glad I was able to help.
Everyone take a second and imagine how insanely large the .blend file for this video must be. Now imagine all the memory cells that contain the data. Imagine how crazily advanced it is that some electrons zooming through metal on a PCB are able to be processed by a CPU, GPU, and an SSD for storage. Then they get sent to a screen on your phone and give you an animation like this. My brain is thinking of all the tiny pieces that go into it and above all I just wonder how the heck it got like this. Amazing video, a gem of TH-cam.

What I find the most mindblowing isn't so much the concept of memory, but the feat of manufacturing these complex structures. I mean, a flash trap has to be the size of what... a fraction of a micron? How do you make something that small, that also has a functon?
