摘要:
A semiconductor device includes a pulse signal generating unit for generating a plurality of pulse signals each of which has a different pulse width from each other, a signal multiplexing unit for outputting one of the plurality of the pulse signals as an enable signal in response to an operating frequency of the semiconductor device, and a duty ratio detecting unit for detecting a duty ratio of external clock signals in response to the enable signal.
