Abstract
A semiconductor chip comprises an internal clock circuit, a first phase shift device, a second phase shift device, a multiplexer, a first output pad, and a controllable pad. The internal clock circuit generates an internal clock signal. The first phase shift device shifts the phase of an external clock signal and outputs a phase shifting clock signal. The multiplexer selectively outputs one of the internal clock signal and the phase shifting clock signal to be a first clock signal. The second phase shift device shifts the phase of the first clock signal and outputs a second clock signal. The first output pad outputs the first clock signal. The controllable pad is controlled to selectively act as an input pad for receiving the external signal, or act as a second output pad for transmitting the second clock signal.
