4bitcelle
4bitcelle is a term used to describe a memory storage cell that stores four bits of information per physical cell. In practice, this corresponds to quad-level memory cells, commonly referred to in the industry as four-bit-per-cell NAND, or QLC. The term is used in discussions of non-volatile flash memory and other high-density storage technologies where increasing the per-cell data count reduces the required silicon area for a given capacity.
Each 4bitcelle must discriminate among 16 distinct voltage levels to encode the 16 possible four-bit combinations.
Implementation typically occurs in NAND flash devices used in solid-state drives and other high-density storage, organized
Historically, four-bit-per-cell NAND gained prominence in the 2010s as a means to achieve larger capacities at
