Yup, I had mis-remembered the SLC versus TLC numbers.
I'm surprised QLC gets as high as 1000, frankly. It's like the cells are on a first-name basis with the electrons they hold.
- wtallis 7y agoI think it was worse with TLC right before the transition to 3D NAND. They were down to about 8 electrons between voltage states. 3D NAND memory cells are physically much larger than 15nm planar NAND, and most are a lot less leaky.
- kabdib 7y agoEIGHT electrons? Indistinguishable from magic, man. [Cue future archeologists: "Remember when our grandparents could only get a few gigabytes on a quark? How primitive, how sooo last-femtocentury."]
- davidcuddeback 7y ago> last-femtocentury You nerd-sniped me. I couldn't resist calculating it. A femtocentury is about 3.16 microseconds.
