How does NAND Flash Work? Reading from TLC : Triple Level Cells || Exploring Solid State Drives

[@scnt4693]

The simplicity with how this channel explains some of the most complicated topics of modern technology and still manages to leave nothing untold is astonishing. I was about to ask exactly how electrons are stored in the charge trap and immidiatly after the video points me toward the answer. This serie is a true work of art. Thanks for sharing.

[@T0M50N]

Agreed, I would normally have no interest in this topic at all but I can't help but watch when it's presented this well.

[@StephenRayner]

Agreed! Absolutely incredible... we need this guy teaching our youth or this style at least.

[@johnnysparkleface3096]

Yeah, I couldn't keep up with the explanation. I believe it was all perfectly explained, but it was all techno-jibber-jabber to me. I would have to watch this 1000 times before any of it made sense.

[@matthewmcclain1316]

Seriously. This guy puts a ton of effort into these videos. And the animations! Again, the animations! They're always exactly what he's talking about and showing. I wonder if he does those as well, or if that's outsourced. Either way, extremely impressive

There’s less of a need for college every year. The tuition cost is exorbitant, the professors are hard to learn from, and free KZbin tutorials are easier to understand than the paid lectures. I’m not sure if I should dropout and learn on my own on my own time and risk a 4 year bachelors degree.

@ yes i think their will come a time when SSD's will need a large cache of faster more durable cells at this rate. Tbh tho i think SSD's are fast enough for most things right now, and RAID exists for anyone who really really needs the fastest speeds.

[@yamatsukami987]

@ well it's not like they are getting slower, just means you might not be able to read dozens of gigs a second off a single SSD without making some compromises if they can't. That said I think we are further from the limits of memory technology than CPU's, it just might take a fundamentally new approach to memory storage.

[@Richie_]

From magnetic core rope memory to this.. Amazing..

[@ubermakee]

Very interesting and informative video, but it raised further questions in my mind as well. For example, how can electrons be removed from the charge trap? If the same voltage increases in all gates in a page, that should attract electrons into the charge trap in every cells. How is that prevented? How can only a single cell be modified? Knowing the general characterictics of an SSD/cheap VNAND, how can a cell be damaged in case of writing and why is it getting worse by increasing its capacity? I would highly appreciate such explanations in a similar, incredible quality educational video.

[@BranchEducation]

I made a video about writing to a cell. Basically the write voltage is 18- 20v and read is 0-4.5v

EXCEPTIONAL LEVEL OF ANIMATION AND CONTENT...BEST EVER SEEN.....💖

[@MichaelDiezFeed]

Great video. As a computer engineer, I found it incredibly useful. The reason I found this video is because I ran into an issue with my Macbook Pro M1. If the free space in my 256GB is below approx 30GB, then the laptop slows down significantly when using memory-intensive programs. So I suspect it has to do with how TLC SSDs write information. What I think is happening is that the space in a TLC SSD is grouped into thirds. So if the drive is nearly full, then the write operation has to move 3-times the data. Something like that, too long to explain in a comment. Would you make a video explaining the write operation of TLC SSDs at nearly full capacity?

[@gabrielferrazdetetivehardware]

I have a small question whaf exactly are those " C.E.(Chips enable if i'm not mistaken)" in each SSD? and when we say this controllar have 8 flash channel, does it mean it can comunicate in paralell with up to 8 NAND flash chips or 8 dies inside a nand chip? For example, lets assume we have a 4 channel controller in a SSD which only has 2 NAND Chips(512GB each for example) but inside of each these 512GB nands, are 4 128GG(1Tb) dies. Does this "4" channel correspond to the number of dies in each nand flash or the amount of nand flash in the PCB. If you have a 4 channel controller with 8 nand flashs then what would happen? Would some of these have to wait in order to comunicate with the controller?

[@EngineeredFemale]

God damn... This whole concept is BIG BRAIN!!

[@chromosome24]

For writes, you'd need just the right amount of current flowing through the channel for the right amount of time to get the right amount of electrons to tunnel to the trap. So write times would be dependent on bit sequence, where the bit sequence associated with the highest voltage quantization will take the longest to write. For example, 010, 100, 001 all have different write times even though each is only writing 1 bit.

[@Destroyer4700]

The sequential write speed of an SSD is not bound by whether it is "consumer" or "enterprise" grade but by the type of interface. The 520MB/s figure is probably the maximum possible speeds using SATA. While the 6,900 MB/s seems to be the figures for SSDs that use PCIe [4.0?]. Even an enterprise grade SSD will run at 500-600 MB/s if it uses SATA.
