Abstract
A memory system comprises a plurality of non-volatile memory cells grouped into blocks of memory cells and a control circuit in communication with the memory cells. The control circuit is configured to program original data to a first block of memory cells and backup the original data by programming a copy of the original data across multiple blocks of memory cells at a word line offset. After being used to store backups of original data, blocks are rotated to be used for storing original data.
