A cache memory and method for controlling the cache memory. The cache memory selects, from an access address, a unique set from among a plurality of sets, each access set including a plurality of cache entries. Each cache entry holds unit data for caching. The cache memory holds, for each of the cache entries, order data that indicates an access order of the cache entries in each set, and replaces a cache entry that is oldest in the access order. The cache memory modifies the order data regardless of an actual access order, and selects, based on the modified order data, a cache entry to be replaced.
