<p><P>PROBLEM TO BE SOLVED: To prolong a service life of a nonvolatile memory including an internal counter. <P>SOLUTION: In a memory driver 22 functioning as an interface between a nonvolatile memory 13 in which the number of times of rewriting is limited and a file system 210, a processor 11 determines whether a writing or reading address is a predetermined value A0. When it is determined that the writing address is A0 (S0 and S1), a value resulting from incrementing a maximum value (Aj)max of a count value by 1 is written in an address where a minimum value (Ai)min among count values stored in addresses A0 to A3 corresponding to the address A0. When it is determined that the reading address is A0, the maximum value (Aj)max of the count values stored in the addresses A0 to A3 is read. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
