ABSTRACT:
A semiconductor device for inputting/outputting data in synchronism with a reference clock signal and an internal clock signal in each circuit. In this device, a variably delay section delays a generated clock signal to output an internal clock signal, and a phase error-detecting section detects a time difference between the internal clock signal and the reference clock signal, thereby controlling the delay amount of the variable delay section to make the time difference substantially zero.
