Abstract: A technique for improving performance of a cache is provided. The technique involves maintaining indicators of whether cache entries are dirty in a random access memory (“RAM”) that has a lower latency to a cache controller than the cache memory that stores the cache entries. When a request to invalidate one or more cache entries is received by the cache controller, the cache controller checks the RAM to determine whether any cache entries are dirty and thus should be written out to a backing store. Using the RAM removes the need to check the actual cache memory for whether cache entries are dirty, which reduces the latency associated with performing such checks and thus with performing cache invalidations.
