A sense amplifier power supply circuit includes an overdriving unit configured to apply a first voltage to a sense amplifier in response to a first enable signal, a sense amplifier driving unit configured to apply a second voltage to the sense amplifier in response to a second enable signal, and a switching unit configured to selectively apply the first voltage or the second voltage to the sense amplifier in response to the first enable signal and the second enable signal.
