FRONT MEMORY STORAGE SYSTEM AND METHOD

摘要

A flash memory storage system (10) includes a memory array (12) containing a plurality of memory cells (14) and a controller (16) for controlling the flash memory array (12). The controller (16) dedicates a first group of memory cells to operate with a first number of bits per cell and a second, separate group of memory cells (14) to operate with a second number of bits per cell. A mechanism is provided to apply wear leveling techniques separately to the two groups of cells to evenly wear out the memory cells (14).
