Abstract:
A memory module comprising a non-volatile cell array and a re-mapper. A page map table is stored in the non-volatile cell array, and includes mappings of old page addresses to new page addresses. The re-mapper is configured to direct memory operations referencing an old page address to the new page address that the old page address is mapped to. The mappings are created when a memory cell is determined to be in a failure state.
