PROBLEM TO BE SOLVED: To provide a pipe latch circuit which is initialized each time read operation is terminated and allows input/output sequence of data latched in a pipe latch to be always matched, and to provide a semiconductor memory device using the same. SOLUTION: The pipe latch circuit includes: a reset signal-generating unit which receives a read-write flag signal and a read period signal and generates a reset signal, wherein the reset signal is enabled after all data are output to an outside upon read operation or upon entry into the write operation; an input/output control signal-generating unit which generates many input control signals and output control signals in response to a read strobe signal and a clock signal, and is initialized in response to the reset signal; and a pipe latch unit which latches input data in response to the input control signals and outputs the latched data in response to the output control signals.
