Abstract

PURPOSE:To prevent processing performance from deteriorating greatly by securing a buffer memory function as it is even when a tag memory becomes unusable. CONSTITUTION:When a tag memory TAG is unusable, a buffer memory BS/TAG signal permits only a comparing circuit 5 to perform comparing operation, and a comparing circuit 4 is disconnected in terms of circuitry. Address information which corresponds to the data of SETO of the BS is stored in the SET2 of the BS, and that to the data of the SET1 of the BS is stored in the SET3 of the BS. Consequently, the capacity of the BS is reduced to half a normal one, but it is reconstituted as a buffer memory for the present.
