PROBLEM TO BE SOLVED: To reduce power consumption of a memory device.SOLUTION: A calculator as one embodiment, which manages a first memory region and a second memory region that consumes less power for holding stored data than the first memory region, includes a data management unit and a data processing unit. The data management unit manages the number of references that is the number of processes referring to first data that exists in the first memory region or the second memory region. The data processing unit moves the first data to the second memory region if the first data exist in the first memory region and the number of references to the first data meets a predetermined first condition. |
