PROBLEM TO BE SOLVED: To provide a memory system for achieving speed-up and an increase in efficiency in data writing processing in non-volatile memory, to which overwriting is inapplicable and to which writing involves block-to-block data move. SOLUTION: Correspondences between logical blocks and physical blocks of first and second memories are controlled such that an identical logical block is subject to correspondence with a physical block of the first memory and to a physical block of the second memory, and data of pages included in an identical logical block is stored such that pages storing data do not overlap between the physical blocks subject to correspondence with the identical logical block, so that processing performed on the first memory and processing performed on the second memory are performed in parallel.
