Abstract
A semiconductor apparatus includes a power supply changing unit. The power supply changing unit is configured to receive an enable signal and power supply voltage, generate first voltage or second voltage according to the enable signal, change a voltage level of the second voltage according to a level signal, and supply the first voltage or the second voltage as a driving voltage of an internal circuit, wherein the internal circuit receives a first input signal to output a second input signal.
