Abstract

In accordance with some embodiments, wear leveling may be done based on the difference in age of discarded blocks and engaged blocks. Data is moved to an older discarded block from a younger engaged block. Two wear leveling bits may be used for each logical block, such that the wear leveling bits are used in alternating cycles.
