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.
Claims37
A semiconductor apparatus, comprising:
- a power supply changing unit 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;
- and
- a swing level adjustment unit configured to adjust a swing level of the second input signal according to the enable signal to output an output signal.
A semiconductor apparatus, comprising:
- a power supply changing unit configured to change power supply voltage in response to an enable signal or a level signal to generate a same first voltage as the power supply voltage or second voltage having a voltage level lower than the power supply voltage and supply the first voltage or the second voltage as driving voltage of an internal circuit, wherein the internal circuit receives a first input signal to output a second input signal and swing the first input signal between the first voltage and ground voltage or between the second voltage and the ground voltage in the internal circuit;
- and
- a swing level adjustment unit to receive the second input signal and output a signal swung between the power supply voltage and the ground voltage in response to the enable signal.
