Patent ID: 7138853

Claim:
A power-boosting system comprising: a first reference voltage generating unit, which generates a first reference voltage using a power supply voltage; a positive voltage power consumption-dependent boosting unit, which generates boosting control information using the power supply voltage, the first reference voltage, and a first positive boosting voltage from an output terminal of the boosting unit, and outputs the first positive boosting voltage, which is obtained by boosting the power supply voltage in response to the boosting control information and adapting to an amount of power consumption at the output terminal; a positive voltage boosting determining unit, which generates first enable information using the first reference voltage, the first positive boosting voltage, and a final positive boosting voltage; a second reference voltage generating unit, which generates a second reference voltage using the first reference voltage; a negative voltage boosting determining unit, which generates second enable information using the first reference voltage, the first positive boosting voltage, the second reference voltage, and the final negative boosting voltage; and a positive/negative voltage boosting circuit, which outputs the final positive boosting voltage, which is obtained by boosting up the first positive boosting voltage and adapting to the amount of power consumption, by selectively performing charge pumping using the first positive boosting voltage or terminating pumping in response to the first enable information, and outputs the final negative boosting voltage, which is obtained by boosting down the first positive boosting voltage and adapting to the amount of power consumption, by selectively performing charge pumping using the first positive boosting voltage and terminating pumping in response to the second enable information.
