Abstract
Provided is a memory access control unit that performs writing by dividing write data and an error correction code thereof into a plurality of memories, and acquires presence or absence of occurrence of a verify error in each of the plurality of memories related to the writing. In a case where the verify errors occur in at least any of the plurality of memories, an error bit length acquisition unit acquires bit lengths of the verify errors from the plurality of memories and a write control unit determines that the writing has succeeded if a total bit length of the verify errors falls within a range of a capability allocated to an error bit length tolerance of the error correction code, and determines that the writing has failed if the total bit length of the verify errors falls outside the range.
