The array 30 is used exclusively for cache access and a 1st hit detecting circuit 50 checks the coincidence between the correspondence information and its parity to decide the presence or absence of a hit. When the discordance of data occurred between a data array 70 and a main memory is checked, the duplicated 2nd arrays 40 and 41 are checked. When the presence of a hit is confirmed, the duplicated 2nd hit detecting circuits 60 and 61 output the logic level '1'. Then a hit is decided when the OR of the outputs of both circuits 60 and 61 is equal to '1'. As a result, the faults of those arrays 30, 40 and 41 can be easily relieved.
