Abstract

A semiconductor device stabilizes an operation of an input buffer. A semiconductor device includes an input potential detection unit, an input buffer, and a current sink unit. The input potential detection unit outputs a detection signal in response to a level of an input signal. The input buffer buffers the input signal by differentially amplifying the input signal through a first current sink unit. The current sink unit receives the detection signal, and in response to the detection signal, performs an auxiliary differential amplifying operation with respect to the input signal buffered by the input buffer.
