- In this video, I am going to explain how Flash Memory and Solid-state drives (SSD) work! Have fun, get some popcorn and enjoy!
Everybody stores pictures, music, and videos on their devices nowadays. The encoded information is even stored when the device shuts down due to low energy. After powering it on again, we find the same media and are glad that it did not disappear.
Flash memory was invented in 1984 by Japanese engineer Fujio Masuoka at the Toshiba Corporation. An electrical storage medium that does not require any energy to retain data. The name "Flash" was suggested by a coworker of Masuoka, Shoji Ariizumi because the erasure process of the newly invented device reminded him of a camera's flash. Later, the invention of flash memory allowed the wide use of solid-state-drives (SSD) that most of us have in their computers today.
The fundamental building block of flash memory is the floating-gate MOSFET, in short, FGMOS. Dependant on the kind of used technology, flash cells can store one or up to four bits (single-level cell (SLC) = 1 bit; multi-level cell (MLC) = 2 bits; triple-level cell (TLC) = 3 bits; quad-level cell (QLC) = 4 bits) - five bits per cell (penta-level-cell (PLC) = 5 bits) is in development currently. In a nutshell, these memory cells are arranged right next to each other and layered on top of one another to realize a highly capable storage medium. This makes it possible to produce a chip with trillions of flash cells, which then can store up to 1 TB of data! A perfect SSD! Flash memory is amazing and you know what? Engineers and semiconductor manufacturers will continue to shrink the size of flash cells in order to improve storage capacity and to reduce the price per bit. Therefore creating even better technology and cheaper solid-state-drives (SSDs) in the future!

This is some of the highest quality content I’ve ever seen on TH-cam. I think you could be making a lot more money from this haha
It's too early for asking for support in patreon.
However, great content and excellent explaination.
Suggestions: please increase frequency of video uploads. May be one per week.
@@abrarshaikh2254 his work is awesome so what is your problem ? and i think its not so easy to make this video...
Cool!
It's very weird to see things going up and down everytime. It's dizzy to me, so THUMB DOWN 👎 for your video.
how did humans come up with this stuff? it is just amazing. true engineers
We used sticks and stones at one point. Somehow we got to this point. I find it fascinating
@@deathrat but I still want to use stick and stones
We were born. Then we had to survive. Then some of us took conscious of their own existence and of its importance as whole, so they painted themselves. Then we recognized the importance and the necessity of living as groups, societies. Then we had to feed them. And because human is a very egocentric and egoistic specie, we had to split ressources according to merit. So we needed a way to keep track of each one's doing for and against the society and each other. Invention of writing.
You can continue that little charade till the invention of computers. Everything is just a matter of need. And luck also. And need to understand too. Human is a specie made to go forward and to solve its own problems.
@@brainloading5543 you just resumed the whole evolution in one string
Alien tech reverse engineered.
I agree with most commenters, this is a quality upload. I bet this took quite some effort. Thank you for a wonderful explanation on flash memory!
Such a high-quality video. You really deserve more views and subs, lol.
Thank you, I'm glad you liked it!
@@blitz8229 me too, thank you
He'll get there, it's only a matter of time :)
MLC is created not by more layers, rather variable voltage levels. MLC (2 bits per cell) simplistic cell data storage example: Voltage stored in cell 0v=00, 1v=01, 2v=10, 3v=11. It takes time and complexity to decode the voltages as well as write them and also there's a higher likelihood of errors due to the analog data hence error correction is needed.
Just got done with a lecture going over flash memory, felt completely lost. Thankfully i found this video and it has made a world of difference. Quality upload!
Underrated Channel Top-notch explanation, this guy deserves much more subscribers.
Wow! Can't believe this video has less view than other with similar explanation. This one has a concise and clear overview explanation on the subject of flash storage. Moreover, the graphics used to explain is original and nice to look at. Thank you, BLITZ!
Bruh, this is a very informative and visually/vocally attractive video on Flash memory. This needs more views.
Absolutely awesome! I was stunned by the quality of your videos, I hope you'll get a lot more subs soon. Keep making such great tutorials, thank you very much!!!
Most underrated TH-camr I will surely share to my frds bro don’t worry you reach great heights
I was really curious about this for a while. Thanks for the video!
Great job on this video. So glad we have all of these super smart people to develop these fun toys.
Just deleted Microsoft flight simulator 2020 off my ssd, it took less than a minute (OVER 100 GB OF DATA). I was curious as to what flash memory is. Great video, great quality, very well explained. Thanks :)
Thank you!
why u deleted it?
@@neilmande5148 couldn't get gut
nice explanation for flash memory. The content is very easy to understand.
Thank you! The video is very high quality! Thank you for the thorough explanation:)
Just what I wanted to know about Memory Cards. Thanks a lot
Tons of appreciation a very comprehensive video
It's 2021, you deserve more subscribers! It is one of the best explanation videos I found on flash memory topic. Come on people, subscribe this channel already!
How does this channel have 2k subs? Thanks for this vid.
Loved it....Very clear information...Thank you
It's crazy how much tech we just take granted. For example we just buy an SD card and never question how we can leave it for years without any electrical input and it just retains the data
Great video. Thank you for sharing!
Great video!! Only the music and sound effects.. are quite confusing xD
i still dont get how this is possible... its trully fascinating how all of this works and cant stand at what point of invention we are at
Great explanation! Thank you.
truly an amazing a explanation! i managed to find the answer to my question))
Great videos man! Keep up the good work
Thank you, i will!
Thanks you so much, this video was really useful.
Nice video. I get a little bit dizzy with the up and down animation, I would recommend to decrease the animation speed a bit. But that maybe it's just me. Thank you for the video.
awesome content bro.
very informative.
hets off to you.
you earned my respect.
Thanks for the video, high quality animations =)
I found the limit of the flash memory on my phone today. 2 years of downloading 100gb every 3 days. Always transferring it to a hard drive. I never thought I'd be able to do it.
Nice video and styling!
Thanks for including captions
Great Video!
Still hoping for some longer Videos!
Thanks!😁⚡
Best explanation with the help of animation.
Great explanation and animation
Really great video! Keep it up!
Wow. Its amazing. Wonderful video
Great video...Awesome explanation but I would like to know the fabrication process of flash memory
Creative video, thank you :)
You are a genius. Thanks for this content!
Great quality. Subscribed. You should have more subs.
Great Video! Thanks a lot!
Great video! Thank you for explaining this. I'm about how many write cycles you can get from a traditional magnetic disk drive? And how long does it really last in each memory type? 🤔
amazing !!!! Thanks a lot ! wirklich sehr gut erklärt
Awesome work 👍
Great video!
thank you so much ..this vedio is so much informative
Very helpful
Thank you very much!!
This youtuber is underrated!! 😤😤😁
Hello Nice Video, I have a question .At 2:52 you are saying that if there are no electrons at substrate then logic zero is assumed as electro are trapped at floating gate so no current will flow through substrate but why we are not measuring current ? without measuring current how shall we will come to know that there is a zero current. What is threshold voltage of flash cell ? what does it mean and suppose you apply voltage more than threshold voltage then what will happen ?
Please reply. Thanks
good video easy to understand
Great video, thanks
Underrated channel
Great Video, keep it up!
Great video,
However I come across terms like sectors on flash.
You said pages are smallest programmable unit and multiple pages make up a block which is the smallest erasable unit.
Which one of these is sector?
This was an amazing video! I have to ask, which software tools did you use to make this? I've software engineering experience and would love to help (for free) in my free time if it would be at all helpful!
Thank you, I appreciate that!⚡
I am using Adobe Illustrator, After Effects, and Premiere Pro to create my explainer videos. Currently, I am looking for motivated people to help me out with the channel and I would be glad if you could send me a description of yourself? For more information, please have a look at the channel description. :)

very informative
@Blitz which one is the drain and which is the source?
still confused but love the vid
So simple once you spend 50mins stressed out having no idea what's going on!
Very Nice Video, seems like a Kurzgesagt Video keep up!
I like the Caribbean background music
Thanks for the explanation! But I hope the diagrams stop swinging up and down...
Just Brilliant........
thank you
Danke 👍🏼
I'm your 100 subscriber
Thank you, I appreciate the support from all of you!
Nice Video! I always wondered how this works!
PS: First! :D
Thank you! New videos coming soon! Subscribe! :)
Please, make more videos on electronics...
Thanks bro
Ohh...... awesome
thanks
It is said that NAND data can only be stored for two weeks at 55 degrees Celsius. If my SSD works at 55 degrees Celsius, does it mean that the controller needs to rewrite the data after every two weeks of operation to prevent data loss? Or rather, after powered on, NAND itself could prevent electronic loss without consuming the lifespan？
perfect.thaaaaaaaaanks
what is the evolution of operating systems?
If you want to read the logical 1, why do you apply 3 volts to the control gate if the flow of electrons only goes from the source to the drain
Well now I know what that small black microchip is inside my old console. 🙃
👍👍👍
But how the floating gate traps the electrons?...
What is difference between Memory card and Flash memory
Brabo
is there a reason why the picture is going up and down 2:19? its annoying!
bro pls dont make everything bouncing up and down, it is harder to concentrate on the image. For example during the explanation with mosfets
I didn't think it was made in Japan 1984
Erasing memories requires heat, which is the same principle as erasing cassettes, which have high-resistance materials that need high heat, such as ultraviolet waves... thank you
Actually most of the work was pioneered in the US, but was modified in Japan
3:37 i don't think the "decades" statement here is true, flash memory loses the data over a pretty reasonable amount of time even in human terms (7+ years)
The soundboard abuse is worse than the morning drive guys on the radio.
WHY COMIC SANS MAN 😭😭😭
Did anyone else notice that the background music is the melody of an old Christian Hymn "Are you washed in the blood"
NOR have more space??
inti nya.
HDD, SSD , USB dan SD card makin canggih .
malah makin murah dengan kapasitas makin besar.
>>jadi inget masa2 flash disk 512mb harga selangit dulu ~
Great video, but the bouncing of everything is annoying. Hopefully I am not prone to sea sickness :-)
I felt that it was not thouroughly explained enough, so I did not get a chance to retain all the facts.
Funny how EEPROMs are writable, and yet have "read only" in their name
What?
The "Jesus Loves Me" playing in the background is a bit distracting.
