PROBLEM TO BE SOLVED: To provide a memory system wherein data reading processing is not affected by a "read disturbance" phenomenon when it occurs. SOLUTION: The memory system includes, in addition to an arithmetic device 50: a plurality of first blocks provided to store information including user information, and each allocated with each of first physical addresses not overlapping each other; and a plurality of second blocks each provided to store the first physical address of an initial defect block of the plurality of first blocks. The arithmetic device 50 obtains the first physical address corresponding to a prescribed logical address, based on a prescribed mirror logical address corresponding to the input prescribed logical address, and information stored in the second blocks.
