Abstract

PURPOSE: To realize an excellent associative memory for address conversion by combining a high-speed small memory with a low-speed mass memory.
CONSTITUTION: With 1st memory unit 100 stored with a couple of a virtual address and actual address, 2nd memory unit 105 is combined which is slower in access and larger in capacity than the 1st memory unit and when a virtual address to be searched reside in the 1st memory unit, a corresponding actual address is immediately outputted. When it resides in the 2nd memory unit 105, the virtual address to be searched and the corresponding actual address are written in the 1st memory unit and the actual address is outputted. In this way, an associative memory can be realized whose shortest time of address conversion time is short.
