ABSTRACT:
An data recording device according to an aspect of the present invention includes a memory cell array in a memory chip, a refresh circuit which executes a refreshing of the memory cell array, a refresh control circuit which executes refreshing at a time interval which is shorter than a data hold time and manages a data hold time, and an internal power source which supplies a power source electric potential to the refresh circuit and the refresh control circuit in a state in which the data recording device is removed from an external device.
