A memory control circuitry has a write destination selector to select either a volatile memory or a non-volatile memory in a first storage as a write destination, for an address area in the first storage written by a processor, a write controller to write data in the write destination selected by the write destination selector, and an access information register to register information selecting the volatile memory or the non-volatile memory as the write destination, and number-of-times information indicating how many times a page of successive addresses for the address area is switched, as both information being associated with each other. When there is a write request from the processor, the write destination selector selects the write destination based on the information registered in the access information register.
