New NAND Storage Development: SLC, MLC, TLC, QLC NAND ... going for PLC

The reason is that the number of bits expressed in a cell's voltage is an exponent.

Flash cells are analog devices (as is everything physical). Each cell "stores" a single particular voltage.

PLC, expressing 5 bits per cell, requires 2^5 = 32 distinct readable / writable voltage levels. 8 would require 2^8 = 256 distinct levels. They're not moving *from 4 to 5*, they're moving *from 16 to 32*.

 

Hilbert, kindly read through the thread and see for yourself who started the personal attacks. Fox always does this, this is not his first time and he does this when he is cornered. OmniDyne remained very very respectful right until it was not bearable anymore.
