ABSTRACT:
A semiconductor device includes a one-shot pulse generating circuit that generates a one-shot pulse having a predetermined pulse width at a rise or fall timing of a first clock signal, a cycle time measuring circuit that measures a cycle-time of the first clock signal from the one-shot pulse output from the one-shot pulse generating circuit, an internal clock generating circuit that generates a second clock signal based on the cycle time measured by the cycle time measuring circuit and the one-shot pulse output from the one-shot pulse generating circuit. The second clock signal has a cycle time identical to the first clock signal and has a rise or fall timing which is advanced by a specific time than that of the first clock signal, and the specific time is obtained by subtracting the cycle time of the first clock signal from a predetermined time, and a data output circuit that outputs data after a predetermined delay time from the rise or fall timing of the second clock signal.
