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.
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.
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
I studied electronic engineering my whole life, and I have never seen such an incredible demonstration ... congratulations for the work done on this channel
Never been this early, I am proud to be studying electronics. I learnt more in these 13 minutes compared to all my cumulative study of a week. Full patreon support to this channel when I get my job!!!
This is the most detailed and most illustrated explanation ever. Thank you for the wonderful work you have done to explain everything in a simple and illustrative way
@@silverliniing Wow, thats crazy how much technology advances in such a short time. I guess I will not gonna be surprise if next year there will be flashdrive sized petabyte version of it soon.. yet here I am commenting using windows 8.1 with 32gb SSD Netbook....😪
I love this channel so much. Everytime an explanation brings up a new question, it is answerd right after. This type of teaching is 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 UA-cam 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.
I can't convey just how wonderfully clear this video made this topic for me, the animations and diagrams are excellent and the narration was perfect, explaining everything step by step, with nothing in between left unexplained for me to ponder. Thank you and well done!
I had so many questions about what a page is, how a cell can store more than 2 values, how does it even work to have all your gates sharing an input, how can multiple cells be read in parallel. This video answered all my questions.
thank you for this video, amazing to have someone doing this, most ppl just care about performance but some of us want to know in which way it achieves performance
These videos are awesome. Not too fast, well versed. May have missing information by any chance but I don't care that much, the whole thought is there for an average person to understand. Kudos
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 Thank You for your reply. :) Keep making such contents, they are really great not just in explanation but in visualization as well! One of the best chanels I subscribed to!
Thank you for this unmatched quality of educational video. I don't think there is any other channel that comes this close to illustrating this simply and with this much sufficiency. But please make lots and lots of videos. There are only few.
Finally.. I now understand where the theoretical Solid State Physics class is applied. Thank you so much. Can't wait to share this and rest of the series.
@ 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.
@ 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.
This is so cool! It's crazy how we can manufacture electronics that are measurable by the atomic scale. It makes me think that connectors on the motherboard (like the SATA and PCIE ports) will shrink once technology grows smaller and smaller.
I really like the detail of information and the good to understand explanations on this channel. As I’m an it administrator and mostly know those things I often point colleagues to your videos because I could not explain such things better then you do.
Very useful! Thanks Branch Education and Kioxia. Btw, the animator did a good job in showing those massive caps on the enterprise version (as opposed to the consumer version which probably lacks these :P ).
Fantastic video. As a med student with 0 engineering background, I found this super easy to understand and loved the concise yet informative animations
What a stunningly excellent and eloquent explanation for NAND. I’ve read the details but I never really thought “how does it function-physically?” Thank you very much! Sub’d.
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?
Hi, I'm an engineer from SamSung Semiconductor, our spec about SSD said data on NAND will be kept for 3 months when poweroff, not years, we give our promise to customers too.
your animations are way better than reality …..awesome job . May god bless you for the educational information you are sharing with your domain of expertise in video editing and theoretical knowledge. Love from India ..!!!!!
I'm so amazed to the way this technology works. It`s incredible how far we can go, makes me fell hopefully about our specie, regardless the way things are nowadays.Also wanna say that the explanation makes it easy to understand.This channel is awesome , congratulations
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.
Fantastic series, I hope your other videos are just as great but this series alone has easily earned a sub from me. Great job at explaining this in a way someone like me (ie not an engineering student) can understand without making it super basic. Thanks for your content
Thank you for these quality education videos! The research, credibility and production quality of these 3D models is very high! You deserve so much more subscribes!
Does reading the cell alter the charge in the charge trap? Edit: just rewatched for the creators comments and they explained alot. Great Idea to fit more info for those who are curious and leave the simplified version for more casual viewers. Fantastic work
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.
Can i use screenshots of this presentation in my own, quick lecture about SSDs? I need it for my university, and i just absolutely adore how detailed and clear everything is
Fantastic video btw! I would love if you did a video on how a traditional platter hard drive works at this level and maybe include how storage density has evolved on this medium. Nice work!
So that means, if the charge trap is slightly bigger, then it can hold more electrons, which will increase the number of possible threshold voltages. The more the number of possible threshold voltages, the more the bits it can store. So to increase the total bit capacity of a cell, we either have to increase the size of the charge trap and subsequently the whole cell to make space for more electrons, or find a way to fit in more electrons in the same size somehow. Correct me if I'm wrong anywhere, this is just my take.
A smaller capacitor will need fewer electrons to reach a given density which, in its vicinity, could thus produce a higher voltage: two electrons very close together could produce a higher voltage than if one is at New York City and the other at Los Angeles. What you can easily get with a larger number of electrons is more precision on the voltages steps. But one the other hand, you cannot have too many voltage steps, otherwise, you could have voltage steps of the same magnitude than, say, thermal noise, or nearby variable electromagnetic fields.
Well, charge trap in reality is an electro magnet which is north and south poles and so data can save for many decades. Not like a transistor in cpu chip which is PN junction mostly, memory chip is mostly electro magnets inside.
It is said that NAND data can only be stored for 4 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 4 weeks of operation to prevent data loss? Or rather, after powered on, NAND itself could prevent electronic loss without consuming the lifespan？
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.
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.

Man this is some the hands down best explanations I have ever seen
this excellent visualisation!, having been in flash industry for last 9 years, this is the first time am seeing such !
The 550MB/sec figure is for SATA SSDs. Thanks to PCI Express and NVMe, there are consumer M.2 drives reaching over 6GB/sec on PCIe 4.0 systems.
The fact that people even designed this technology is so remarkable to me
