Abstract
A semiconductor device stabilizes an operation of an input buffer. A semiconductor device includes an input potential detection unit outputting a detection signal in response to a level of an input signal. An input buffer buffers the input signal by performing a differential amplifying operation through a first current sink unit. A second current sink unit, sharing an output with the input buffer, differentially amplifies the input signal of the input buffer in response to a level of the detection signal.
