Abstract
A counting module counts a number of accesses to a first region of a storage medium during each of a first period and a second period. A count comparing module compares the number of accesses during the first period and the second period and determines whether the number of accesses during the second period is greater or less than the number of accesses during the first period by a predetermined amount. The region defining module splits the first region into two or more regions if the number of accesses during the second period is greater than the number of accesses during the first period by the predetermined amount, and merges the first region into a second region if the number of accesses during the second period is less than the number of accesses during the first period by the predetermined amount.
