A first counter detects a rising edge of a clock signal, and generates a first signal having a multiplied cycle of the clock signal.A second counter detects a falling edge of the clock signal, and generates a second signal having a multiplied cycle of the clock signal. A first line transfers the first signal, while a second line transfers the second signal. A phase comparator is connected to the first line and the second line to generate a third signal based on a phase difference between the first signal and the second signal and output the third signal to one of the circuit units.A plurality of the phase comparators are connected to the first line and the second line, and are disposed between one of the ends of the first line and the second line and one of the circuit units.

A semiconductor memory device includes an interface unit connected to an external circuit, a data memory unit including a write data line, a read-out data line, a data control unit, and a memory block connected to the data control unit, and a read-out latch block connected between a read-out data line and the interface unit. The data control unit outputs data read out of the memory block to the read-out data line with a trailing edge of a clock being used as a trigger. The read-out latch block latches the data with a trailing edge of another clock, which is generated at least one cycle after the trailing edge of the aforementioned clock, being used as a trigger. The interface unit outputs the data to the external circuit with a leading edge of still another clock, which follows the aforementioned another clock, being used as a trigger.
