Management device, information processing apparatus, and memory control method

A management device for controlling readout and writing of data that are performed by a processing circuit with respect to a non-volatile memory storing a plurality of pages, the management device comprising:

• one or more processors configured to perform:
• access processing including performing writing or readout with respect to data stored in the non-volatile memory, in a case where a request for writing or readout is received for any page of the plurality of pages;
• and
• management including controlling a storage position in the non-volatile memory for each of the plurality of pages, wherein
• the non-volatile memory includes a high-temperature region and a low-temperature region in which temperature is relatively lower than in the high-temperature region during operation, and
• the one or more processors are configured to, at the management, move storage positions of the plurality of pages in such a manner that pages included in a high access page group are stored more in the low-temperature region than in the high-temperature region, where the plurality of pages are classified into the high access page group in which access amounts are relatively high, and a low access page group in which access amounts are relatively low.
