PROBLEM TO BE SOLVED: To execute refresh processing of data at an appropriate timing corresponding to a degree of progress of a rewrite frequency of a cell in a memory controller loading type non-volatile memory device.SOLUTION: Provided is a controller of a non-volatile memory device for which refresh processing of data is required. The memory device includes: a non-volatile memory part allowing for rewriting data; a memory controller for controlling reading and writing of data from and to the memory part; and a life management part for managing life information indicating life state of a cell of the memory part. The control device is configured to acquire the life information from the memory device, and to set execution timing of the refresh processing corresponding to the acquired life information, and to instruct the memory device to execute the refresh processing when the set execution timing arrives.SELECTED DRAWING: Figure 3 |
