Abstract:
A method for data storage in a memory that includes multiple analog memory cells, includes defining, based on a characteristic of the memory cells, an uneven wear leveling scheme that programs and erases at least first and second subsets of the memory cells with respective different first and second Programming and Erasure (P/E) rates. Data is stored in the memory in accordance with the uneven wear leveling scheme.
