INFORMATION RECORDING APPARATUS THAT PERFORMS REFRESH OF MEMORY AND CONTROL METHOD THEREFOR

摘要

An information recording apparatus which is capable of preventing data loss due to a decrease in a time period for which data is retained in a memory, and performing refresh of the memory mounted on a main body of the information recording apparatus. When the number of times of data erasure in the memory is updated, a table showing data retention time periods corresponding to the number of times of data erasure in the memory is referred to, and a date and time at which refresh of the memory should be performed within a data retention time period corresponding to the number of times of data erasure is set. Whether it is possible to perform refresh of the memory at the set date and time is judged, and when it is possible to perform refresh of the memory at the set date and time, refresh of the memory is performed.

1. An information recording apparatus comprising:
a memory; a refresh unit configured to perform refresh of said memory; a table configured to show data retention time periods corresponding to the number of times of data erasure in said memory; a setting unit configured to refer to said table and set, based on the number of times of data erasure in said memory, a date and/or time at which refresh of said memory should be performed within a data retention time period corresponding to the number of times of data erasure; and a control unit configured to, based on the set date and/or time at which refresh of said memory should be performed, cause said refresh unit to perform refresh of said memory.
