CACHE MEMORY STORE SYSTEM

PURPOSE:To perform the store reflection processing at a high speed to a cache memory in preparation for the following read processing without increasing the cache busy probability. CONSTITUTION:A comparator group 108 compares the address included in a store address buffer 102 with a read request address after a cache coincidence processing request address received from a normal cache queue 105 referred to a flash address array 113 in preference to the store address received from the buffer 102. Then the coincidence is secured between both addresses, the array 113 is referred to with the preference given to the store address received from the buffer 102.
