ABSTRACT:
A semiconductor device includes a first input terminal, the first input terminal being supplied with an input signal, an input detection circuit including a delay circuit having a second input terminal and an output terminal, the input detection circuit detecting a shift in the input signal and generating a first pulse signal in response to the shift, the input detection circuit being connected to the first input terminal, and a control circuit for generating control signals, each of the control signals being generated in response to a synchronous operation or an asynchronous operation respectively.
