PROBLEM TO BE SOLVED: To reduce a capacity of a memory in which data processed by a processor are stored. SOLUTION: Upon receiving a write request to write write-data Y into an address Bn of a memory region RB issued by the processor 1, a memory controller 2 determines whether read-data X requested to be read from an address Am of a memory region RA by the processor 1 are matched with the write-data Y instructed by the processor 1 so that the data are requested to be written into the address Bn of the memory region RB , and if the read-data X are matched with the write-data Y, prevents the write-data Y from being written into the address Bn of the memory region RB.
