PURPOSE:To prevent processing performance from being lowered due to the increase of the registration of a resident file, by stocking the address of a linking means at the forefront of the resident file linked at every memory unit number by a resident file registering/linking means in a linking forefront address stocking means. CONSTITUTION:Responding to a request to use a cache memory from a processor 4, the address of the linking means at the forefront of a memory unit to be used is read out from the linking forefront address stocking means by using the memory unit number of a request file. And a resident file registering address is read out from the resident file registering/linking means 6 by the above address. Afterwards, the memory unit number is read out from a resident file registering means 5 by the address, and the memory unit number is compared with a requested memory unit number, thereby, the residence/non-residence of the request file is decided. In such way, it is possible to obtain a cache memory control system in which the processing performance is prevented from being lowered even when the number of registration of the resident file is increased.
