Abstract
A gate circuit is turned on in synchronization with an internal clock signal at a timing faster than activation of an output buffer circuit, and internal data is transmitted from the gate circuit to an output buffer circuit externally outputting data. Generation of an internal clock signal is stopped at a timing faster than deactivation of the output buffer circuit, and the gate circuit is set to the latching state. According such arrangement, output of invalid data is prevented.
