Another comment suggest that NAND chips use 8 different voltages / states to encode 3 bits just in voltage states.

- phkahler 2y agoFor data storage, not computation.
- tossandthrow 2y agoI don't really understand that distinction? What makes data storage inherently different on the gate level? Solving that issue has some characteristics that makes multistate voltage a good choice, but sure, that is the circumstances under whish you would use it.
- davrosthedalek 2y agoYes, and there is considerable electronics required in the readout logic to make sure that they are identified correctly, including error correction. That's not practicable for anything but storage or maybe off-chip/high-speed connections.
- davrosthedalek 2y agoActually, I have to correct myself. Charge levels, not voltage levels, and you do not necessarily need to have multiple voltage levels on the driving side to set these charge levels, you can do it by varying the write time.
