ABSTRACT:
A shared cache in a computer system for caching both system memory information and alternative memory information. The present invention includes cache management logic, a cache memory with a plurality of cache lines and a and a cache tag memory. The cache tag memory comprises an address field and status bits for indicating a status of corresponding information in cache memory. The status bits, when interpreted as a group, indicate the status of the corresponding information in cache memory as well as whether the information in the corresponding cache line is related to the alternative memory or the system memory.
