1. A voltage generation circuit comprising:
a voltage generation unit configured to generate a reference voltage using a power supply voltage and output the reference voltage through a voltage output node;
a pre-charge unit configured to drive the voltage output node using the power supply voltage in response to a pre-charge control signal; and
a pre-charge control unit configured to generate at least one sampling voltage using the power supply voltage and generate the pre-charge control signal according to a result obtained by comparing the at least one sampling voltage with the reference voltage.
