A cache memory controller and a cache memory managing method using the same are provided to efficiently manage the cache memory at a high speed by selecting an entry not including an address of data, which is requested by estimating the address of the data requested after the presently requested data, as the entry to be replaced. An address estimator(11) estimates the address of the data to be requested by receiving the address of the requested data from the outside. A replaced entry selector(12) selects the entry not including the address estimated in the address estimator as the entry to be replaced from the cache memory if the data requested from the outside is not found in the cache memory(20). The replaced entry selector selects the replaced entry by at least one of an LRU(Least Recently Used), MRU(Most Recently Used), or FIFO(First Input First Output) mode. If the replaced entry does not include the estimated address of the data to be requested, the replaced entry is finally selected as the entry to be replaced.
