ABSTRACT:
In an apparatus for use in a computer system for accessing to a main memory when a desired datum is not memorized in a cache memory, a supplementary memory is included in the apparatus for memorizing a supplementary datum representative of a predetermined address in the main memory. When the desired datum is not memorized in a particular address of the cache memory, a judging circuit produces a particular signal. By a combination of the supplementary datum and the particular signal, an access control part accesses to the main memory to read a specific datum of the main data as the desired datum from the main memory. The specific datum is stored in the particular address from the access control part. The described system can be used for both tagged and untagged data, allowing for compatibility between data systems using different tagging schemes.
