Abstract
A computer system cache memory has a caching tag which stores a subset of the L2 cache memory tag store. The caching tag is smaller, faster memory device than the L2 cache memory. The cache memory latency is reduced because the tag access time and tag comparison time are improved due to the caching tag. The caching tag may be manufactured to be located on the same chip as the cache controller, which allows faster data access than if the caching tag is located on a separate chip.
