APPARATUS AND METHOD FOR MANAGING DATA ACCESS COUNT

摘要

An apparatus counts, for each piece of data, an access count indicating a number of times of access to the each piece of data for every unit time so as to store a management information element including the access count and identification information identifying the each piece of data. The apparatus deletes, from the plurality of management information elements stored in a memory, a management information element that includes the access count having a value minimum among the plurality of management information elements, when a number of the plurality of management information elements reaches a predetermined number. The apparatus determines whether there is a piece of data that satisfies a condition related to rapid increase of access, based on the access counts included in the plurality of management information elements.
