ABSTRACT:
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 frequencies of external clock signals, and a duty ratio detecting unit for detecting a duty ratio of the external clock signals in response to the enable signal.
