Abstract
An address comparator stores an address of data read out by a host system. Also, a buffer reads out the data from a memory and stores the data. If an address of data which is expected to be newly read out by the host system is included in addresses which have already been stored in the address comparator, the host systemnewly reads out the data from the buffer, not from the memory. As a result, it is possible to eliminate or lessen the possibility of unintentional rewriting of data which is likely to be caused due to repeated readout of data.
