ABSTRACT:
A semiconductor device for accepting a data from outside in synchronization with data strobe signal. The semiconductor device includes control circuit for generating an accept-control signal which is activated in response to a write command inputted in synchronization with a clock signal and is inactivated in response to the data strobe signal in synchronization with the final data signal, and data input circuit for accepting the data signals while the accept-control signal is activated. The timing of the accept-control signal varies in accordance with the variation of the timing of the data strobe signal because the control circuit controls so as to inactivate the accept-control signal in response to the data strobe signal. Hence, inactivating of the accept-control signal is always performed within a predetermined time period after the final data signal is accepted in synchronization with the data strobe signal. As a result, the inactivating of the accept-control signal is accurately controlled in synchronization with the data strobe signal. Therefore, only necessary write-data are reliably accepted even if the timing of the data strobe signal varies.
