1. A cache memory control method which is intended for a cache memory comprising at least two memory units, and in which allowance/disallowance of a cache refill is set in advance for each memory unit, the memory unit of the cache memory, for which the cache refill is set to be allowed, is selectively accessed to perform a first cache hit/miss determination, and the access to the cache memory is ended at the time of a cache hit, wherein when the first cache hit/miss determination results in a cache miss, the memory unit of the cache memory, for which the cache refill is disallowed, is selectively accessed to perform a second cache hit/miss determination.
