Abstract
The input buffer circuit of a semiconductor apparatus includes a first buffering unit that that is activated by a voltage level difference between a first voltage terminal and a second voltage terminal, and generates a first compare signal and a second compare signal by comparing the voltage levels of reference voltage and an input signal; a control unit that controls the amount of current flowing between the second voltage terminal and a ground terminal by comparing the voltage levels of the reference voltage and the second compare signal; and a second buffering unit that generates an output signal by comparing the voltage levels of the input signal and the first compare signal.
