Abstract
The memory device comprises a cache memory indexed by the cache index and group information of the virtual address. The physical address translated from the virtual address contains primary and secondary group information. If the tag of the cache entry addressed according to the above standard by indexing of the cache memory corresponds to the physical address, indexing is carried out again using the second group information associated with the physical address (and using the cache index of the virtual address). If the tag of the cache entry thus addressed still does not correspond to the physical address, a cache miss is signaled.
