Abstract

A semiconductor memory device of the invention is provided with a usual access mode and a rapid access mode. The semiconductor memory device includes: a change detection circuit, provided for each of bit signals which are a part of an address signal, for detecting a change of the address signal; a timer circuit for, when the change detection circuit detects the change of the address signal, generating a signal indicating the change of the address; and an output circuit for outputting the signal generated by the timer circuit as a signal which controls a wait of access in each of the access modes.
