A memory device according to one embodiment of the present invention has a memory chip in which a magnetic memory is used, and a memory controller for controlling a read/write to the memory chip. When a read request is received from outside of the memory controller, the memory controller transmits a read command to the memory chip, thereby reading data from inside the memory chip. The memory controller also transmits an update command to each of the areas of the memory chip, thereby writing back the data stored in the memory chip. |
