Abstract
A computer cache for a memory comprises a data random-access memory (RAM) containing a plurality of cache lines. Each of the cache lines stores a segment of the memory. A tag RAM contains a plurality of address tags that correspond to the cache lines. A valid RAM contains a plurality of validity values that correspond to the cache lines. The valid RAM is stored separately from the tag RAM and the data RAM. The valid RAM is selectively independently clearable. A hit module determines whether data is stored in the computer cache based upon the valid RAM and the tag RAM.
