ABSTRACT:
Methods and apparatus for maintaining an average erase count in a system memory of a non-volatile memory system are disclosed. According to one aspect of the present invention, a method for determining an average number of times each block of a number of blocks within a non-volatile memory of a memory system has been erased includes obtaining an erase count for each block that indicates a number of times each block has been erased. Once all the erase counts have been obtained, the erase counts are summed, and an average erase count that indicates the average number of times each block of the number of blocks has been erased is created by substantially dividing the sum by the number of blocks.
