Abstract
A memory system has a non-volatile memory used as a first cache memory to be accessed at a higher speed than a main memory, a first translation lookaside buffer that stores address conversion information indicating the conversion of a virtual address issued by a processor into a physical address, and a first control circuitry that stores the address conversion information stored in the first translation lookaside buffer in the non-volatile memory during a power off.
