The memory chips in an ssd are layered, not stacked.

Nope, stacked. They are vertically connected to each other, not just layered on top of each other.

Stacked = Different chips placed on top of each other connected with ball point grids or whatever in between.

Layered = One chip, internally made in layers or stacks connected with vias.

Memory chips in ssds are layered chips (I think the record is around 96 layers?)

I know it's semantics in the end.
