Abstract
A computer system may include a processor; a first memory device; a second memory device; a cache memory including a plurality of cache entries and a cache controller. The cache controller is configured to manage a flag indicating whether a caching data is provided from the first memory device or the second memory device. The cache controller determines a cache entry to be evicted from the cache entries based on a cache miss ratio and a cache occupancy ratio.
