PROBLEM TO BE SOLVED: To suppress degradation in processing capability resulting from copy processing during garbage collection.SOLUTION: A data storage system 100 according to the present invention comprises: a memory unit 110 that includes a memory 114 to which data is written for every page and a memory control unit 112 for controlling writing of the data to the memory 114; and a control unit 120 for indicating a logical page address that is a data writing destination to the memory control unit 112. The memory control unit 112 determines a target block that is an erasure target block at a time of garbage collection to be executed next, and provides information on the logical page address corresponding to a physical page address of an effective page in the target block to the control unit 120. The control unit 120 transmits an instruction to the memory control unit 112 to write data to the logical page address received from the memory control unit 112. |
