PROBLEM TO BE SOLVED: To shorten an access time by unnecessitating insertion of read-out access to a transient period which is performed because there is a possibility of rewriting the data of an address to which no write-in-access is intended at the transient period of change in an address signal when an externally specified address is changed. SOLUTION: A circuit 30 for forcibly changing an operation state changes an internal circuit operation into a read-out operation state when the change of an address signal is detected by an address transition detecting circuit 10, a write-in signal (WE bar) is in a L state and write-in access is externally specified. Thereby insertion of read-out access for the transient period can be unnecessitated.
