Abstract
Reduced spatial redundancy of lower bits data provides data protection for a flash memory having MLC NAND devices operated in page mode. An interrupted write operation of most significant bit pages can corrupt previously written data in lower bit pages. The lower bits redundant memory assists in restoring the data, using less than a full back up storage.
