ABSTRACT:
A cache memory device comprises a secondary tag RAM that partially constitutes a secondary cache memory and employs a set associative scheme having a plurality of ways, and a secondary cache access controller that, when the number of ways in the secondary tag RAM is changed, allocates tags to respective entries so that the total number of entries constituting the secondary tag RAM and the total number of entries after the number of ways is changed are constant.
