Abstract:
A semiconductor apparatus includes a reference voltage generating circuit and a buffer. The reference voltage generating circuit may generate, based on a voltage setting signal, a first reference voltage and a second reference voltage, which has the same level as the first reference voltage or has a lower level than the first reference voltage by an amount of a unit level. The buffer may generate an output signal based on the first reference voltage, the second reference voltage and an input signal.
