Abstract
A method for intra-block wear leveling within solid-state memory subjected to wear, having a plurality of memory cells includes the step of writing to at least certain ones of the plurality of memory cells, in a non-uniform manner, such as to balance the wear of the at least certain ones of the plurality of memory cells within the solid-state memory, at intra-block level. For example, if a behavior of at least some of the plurality of memory cells is not characterized, then the method may comprise characterizing a behavior of at least some of the plurality of memory cells and writing to at least certain ones of the plurality of memory cells, based on the characterized behavior, and in a non-uniform manner.
