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