USE OF 8-BIT OR HIGHER A/D FOR NAND CELL VALUE

摘要

A system and method, including computer software, for storing digital information uses multiple NAND flash memory cells (124). Each memory cell (124) is adapted to receive charge during a write operation to an analog voltage that corresponds to a data value having a binary representation of more than 4 bits. An analog-to-digital converter (142) converts the analog voltage from each memory cell into a digital representation of the analog voltage (360) during a read operation (350) of each cell.
