today I learned that we (as a civilization) now can put 16 silicon flash dice into a single 700µm microSD card on a commercial scale https://www.ose.com.tw/en/ic-services/memory-product-package/microsdsd

@jernej__s @amy I had the same experience (I plugged it into my Steam Deck)
@whitequark @amy Hey, I just found another 1TB microSD card I forgot about!

@whitequark and all that just to create a storage format that's too small for human hands to handle.

@cm shhhhh... if you say that too loudly they'll make a nanoSD card

if you think that the precariously balanced tower of flash above is an inaccurate representation of what's going on, i can reassure you that
(a) this is exactly how it looks like, and
(b) SK Hynix is up to 24 layers already (not sure in what application)https://news.skhynix.com/semiconductor-back-end-process-episode-4-packages-part-2/

When are people going to be buying old cards on eBay to scavenge the gold wire? -

@whitequark .7mm ea * 16 = 11.6mm thick not inc. substrate........ thats a beefy card.?

@whitequark oh wait, yea, its too early for me to be making social media posts, going to go get coffee. bbl.

@whitequark
Yup. I made a few bucks selling obsolete chips that happened to have gold plated caps… -

@whitequark is this what the Tower of Babel looked like before it fell

@whitequark @RealGene although almost anything made in the last 10ish years is copper bonded now

@whitequark Is this "3D NAND" and similar? I always wondered how they achieved the stacking!

@whitequark also each flash die has several hundred layers of stacked bit cells

@azonenberg yep! Samsung got up to 400 layers last year
-

@attie no, 3D NAND is having (up to 400 in recent flash) layers of NAND cells in each die

@whitequark the last one i threw in the fib was "only" 176 iirc

@whitequark also looking at that diagram it seems like the 16 die stack is actually two 8 die onfi channels on top of each other mirrored with one coming out the left and one out the right

@whitequark now if we'd only build flash for a purpose other than storing content that's been stolen by our AI overlords

@whitequark Oh, intriguing - thanks!
