Abstract
A semiconductor memory device has an operational mode such as a nibble mode or page mode, a first address strobe signal is kept in an active state, and a second address strobe signal is successively switched between an active state and standby state, thereby enabling successive data output. Previous output data is reset once, in accordance with the switchover of the second address strobe signal to the active state while the first address strobe signal is in the active state, before outputting data, and the reset operation for outputting is also performed when both the first and second address strobe signals are switched to the standby state, so that the period in which the data is output is expanded.
