Upon copying data stored on a page in a copy source block of a nonvolatile memory (104) to a page of a copy destination block, an access control unit (108) of a memory controller (103) copies data stored on a page associated with a first copy method to a page of the copy destination block after error correction by an error correction control unit (109), copies data stored on a page associated with a second copy method to a page of the copy destination block without performing the error correction by the error correction control unit (109) according to a copy mode stored in a copy mode storage area, and changes the copy mode associated with the copy destination block to a copy mode that is different from the copy mode of the copy source block.
