PROBLEM TO BE SOLVED: To improve the utilization efficiency of a bus when a read access based on identical bank identification information continuously occurs in a memory mirror configuration.SOLUTION: A memory controller 501 controls access to a memory which is divided into a plurality of operation units. A first operation unit and second operation unit, out of the plurality of operation units, constitute a memory mirror. A reception unit 511 receives a plurality of read requests that include bank identification information for both a first bank that is included in the first operation unit and a second bank that is included in the second operation unit. A determination unit 512 determines an access target for each read access so that a plurality of read accesses based on the plurality of read requests are performed alternately for the first operation unit and second operation unit. A control unit 513 controls each of the read requests so that each of the read accesses is performed for the operation unit determined as the access target. |
