<P>PROBLEM TO BE SOLVED: To provide a semiconductor device incorporating a high-speed input interface for speeding up and improving the operating margin. Ž<P>SOLUTION: The semiconductor device has: a first and second pulse input circuits to input complementary first and second pulses after comparing them respectively with the reference voltage; and a plurality of data input circuits for taking in the input signals corresponding to the data consisting of a plurality of bits with their change start points made the same as the first and second pulses after comparing them with the reference voltage. It forms a third pulse having the change timing set up between the change timing of the output signal of the first pulse input circuit and the change timing of the output signal of the second pulse input circuit by using a phase interpolation circuit. It delays the third pulse for the predetermined time by using a delay circuit. Further, it takes in the output signal of the data input circuit by using a latch circuit corresponding to the change timing of the delay signal of the third pulse formed in the delay circuit.
