Abstract:
1. An information processing apparatus comprising: a central processing unit configured to: manage a rewrite frequency of a page included in a nonvolatile primary storage apparatus having an upper limit in the rewrite frequency; write, when an instruction for writing write data to a predetermined page is issued and a rewrite frequency of the predetermined page reaches a threshold value that is less than the upper limit of the rewrite frequency of the nonvolatile primary storage apparatus, the write data to another page different from the predetermined page, the other page storing no effective data and having a rewrite frequency that does not reach the threshold value; and calculate, when the rewrite frequencies of the pages are greater than or equal to the threshold value, a new threshold value that is greater than the threshold value and less than or equal to the upper limit, and update the threshold value.
