ABSTRACT:
A cache memory management unit that performs searches in a cache memory unit that supplements a disc memory that serves a digital computer. When the computer needs to write a chosen data block into, or read a chosen data block from, its disc memory, the unit first performs a search for the tag or identification label for the chosen data block in the cache memory unit, before the computer searches the disc memory. The unit also implements an algorithm that identifies the least recently used and most recently used cache data blocks.
