Zusammenfassung:PROBLEM TO BE SOLVED: To provide a semiconductor memory device having a circuit for storing access data. SOLUTION: The semiconductor memory device includes a memory cell array and a storage for storing the access data. The propriety of access to the memory cell array is determined by the access data stored in the storage. As a result, the memory cell array is accessed only when required by the access data, thus reducing power consumption. COPYRIGHT: (C)2006,JPO&NCIPI
