[Problem] To be capable of improving the efficiency of accessing a large-capacity cache memory. [Solution] A cache memory system is provided with: a first cache memory of the kth order; a second cache memory having larger memory capacity than the first cache memory and using a non-volatile memory to be accessible faster than can a main memory be accessed; and a translation lookaside buffer for storing information on address translation from a virtual address issued by a processor to a physical address and information on a flag for recording whether data is stored in the second cache memory in page units larger in data amount than cache lines in which units the first cache memory is accessed. |
