Abstract
A non-volatile semiconductor memory is disclosed comprising a memory device including a plurality of memory segments. A program command is issued to the memory device to program a memory segment, and a program time required to execute the program command is saved. An erase command is issued to the memory device to erase the memory segment, and an erase time required to execute the erase command is saved. A wear leveling algorithm is executed for the memory segment in response to the program time and the erase time.
