ABSTRACT:
The present invention discloses a circuit providing a power for a sense amplifier that stabilizes a power voltage supplied to the sense amplifier by compensating a noise generated in the power voltage when the sense amplifier operates with an selectively generated decoupling noise. The circuit providing a power for a sense amplifier includes a sense amplifying circuit sensing and amplifying data loaded on a bit line with a first power. A power supplying unit provides the first power to the sense amplifying circuit. A decoupling unit generates a decoupling noise with a second power and provides the decoupling noise to the first power voltage. The decoupling noise is maintained for a period including a time point of an operation of the sense amplifying circuit and a predetermined time thereafter.
