Abstract:
A non-volatile storage apparatus includes a set of non-volatile memory cells and one or more control circuits in communication with the set of non-volatile memory cells. The one or more control circuits are configured to map the set of non-volatile memory cells into a plurality of regions, apply a first wear leveling scheme in a first region of the plurality of regions, and apply a second wear leveling scheme between the plurality of regions.
