ABSTRACT:
Methods and apparatus for performing wear leveling in a non-volatile memory system are disclosed. According to one aspect of the present invention, one method for processing elements included in a non-volatile memory of a memory system includes obtaining erase counts associated with elements and grouping a number of the elements into a first set. Each element has an associated erase count that substantially indicates a number of times the element has been erased. Grouping the number of elements into the first set includes selecting elements included in the plurality of elements which have the lowest associated erase counts of the erase counts associated with the plurality of elements. The method also includes storing the erase counts associated with the first set in a memory component substantially within a table.
