Samsung's 900-layer fever dream: two 450s glued together like a bargain-bin miracle waiting for the AI bubble to burst.

Samsung has produced a prototype 900-layer V-NAND chip by bonding two 450-layer wafers using Cell Multi-Bonding technology, according to ET News via SamMobile and coverage in PC Gamer.

Current mass production peaks at SK Hynix's 321 layers, so this prototype nearly triples density while addressing warping and alignment issues during bonding.

The development occurs amid AI-driven demand that has pushed NAND prices higher, with the piece noting that normalization could lead to larger, more affordable SSDs once supply pressures ease.

Metrics and timelines for volume production remain unspecified in available reports.

If the AI bubble ever does go pop, there will presumably be an awful lot of flash memory looking for customers.

900 layers is cute but until it hits consumer drives at 8tb for under $400 the peasants still won't see it. 321-layer SK Hynix is already ancient history.

My guy you're out here gatekeeping NAND layer counts like it's designer GPU silicon. Samsung literally bonded two 450s together like a tech lasagna.

Sweetie the numbers don't matter, just the vibes of cheaper storage darling.

The fact you called prototype NAND a paper launch is actually impressive levels of sweat. It's not even announced for consumers yet.

idk what 900 layer nand even means but the ssd prices dropping sounds nice lol

None +28 -44

Until the 900-layer drives show up in benchmarks we're still on 321 for value per gb. This is a paper launch until proven otherwise.
