PURPOSE:To simplify a fault processing by securing such a system where the presence of the requester information within a data array is shown regardless of the retrieving result when a fault is detected in the request information given from the requester. CONSTITUTION:The partial data stored in a main memory 300 and the address of said data are held by a data array 224 and an address array 211. A request selection means 208 selects one of the requests of the requesters 101-103 and informs it to a selection means 207. The fault detection means 201-203 detect the faults of the requests given from the requesters 101-103. If a fault is detected, a forcible hit means 220 shows a cache hit regardless of the deciding result obtained by a comparison means 212 for presence or absence of the cache hit. Then a 2nd control means 221 processes the fault in a hit process.
