VOLTAGE GENERATION CIRCUIT

摘要

A voltage generation circuit includes a plurality of voltage generation units each configured to include an internal voltage with a reference voltage, generate a detection signal based on a comparison result between the internal voltage and the reference voltage, and adjust the level of the internal voltage in response to an oscillation signal, a control unit configured to generate an oscillation control signal in response to the detection signals, an oscillator configured to generate the oscillation signal in response to the oscillation control signal, and a selective output unit configured to selectively supply the oscillation signal to one or more of the plurality of voltage generation units in response to the detection signals.

1. A voltage generation circuit, comprising:
a plurality of voltage generation units each configured to generate an internal voltage in response to an oscillation signal; and an oscillator shared by the plurality of voltage generation units and configured to generate the oscillation signal, wherein the oscillation signal is supplied only to a one or more of the plurality of voltage generation units that output internal voltages each deviating from a target level.
