Abstract
A data recording device includes: a non-volatile memory; a high-functional non-volatile memory characterized by a processing speed faster than a processing speed of the non-volatile memory; and an access controller that controls writing of data into each of the non-volatile memory and the high-functional non-volatile memory, based on an indicator related to a temperature of the non-volatile memory. The access controller (a) writes data into the non-volatile memory when the indicator satisfies a first condition, and (b) writes data into the high-functional non-volatile memory and transfers the data from the high-functional non-volatile memory to the non-volatile memory when the indicator satisfies a second condition.
