Toshiba Memory Corporation, the world leader in memory solutions, today announced development of the world’s first[1] BiCS FLASHTM three-dimensional (3D) flash memory[2] with a stacked cell structure. The newest BiCS FLASHTM device is the first to deliver 4-bit-per-cell (quadruple-level cell, QLC) technology, advancing capacity beyond that of triple-level cell (TLC) devices and pushing the boundaries of flash memory technology.
Multi-bit cell flash memories store data by managing the number of electrons in each individual memory cell. Achieving QLC technology posed a series of technical challenges, as increasing the number of bit-per-cell by one within same electron count requires twice the qyzwfpda cf GPR qeqlizcytu.
