Patent ID: 8743646

Claim:
A semiconductor device comprising: a virtual power supplier configured to boost a driving voltage to generate a virtual voltage; a driving signal generator configured to generate a boosted driving signal from supply of the virtual voltage, the boosted driving signal having a voltage level that is boosted as compared with a voltage level of a driving signal that is generated when the driving signal generator is supplied with the driving voltage; and a load driver configured to drive a load based on the driving voltage and the boosted driving signal, wherein the driving voltage includes a ground voltage and a power supply voltage, and wherein the virtual power supplier is configured to boost at least one of the ground voltage and the power supply voltage to generate at least one of a virtual ground voltage and a virtual power supply voltage, the virtual ground voltage having a voltage level lower than a voltage level of the ground voltage, the virtual power supply voltage having a voltage level higher than a voltage level of the power supply voltage.
