Abstract

Write performance of a block-based multi-level cell non-volatile memory is increased through the use of an internal copy of blocks with a high validity. Write (program) performance for sequential workloads is increased by moving the data in blocks with a high validity within a NAND device directly from the portion of the NAND device configured as single level cell NAND to the portion of the NAND device configured as multi-level cell NAND.
