1. A voltage supply circuit comprising:
a signal generation circuit configured to generate an active mode enable signal according to a chip selection signal provided from an external device, and generate a standby mode enable signal using an external voltage provided from the external device;
an active voltage regulator configured to receive the active mode enable signal and output an active mode operation voltage when the active mode enable signal is in a high state; and
a standby voltage regulator configured to receive the active mode enable signal and the standby mode enable signal, and output a voltage lower than a standby mode operation voltage outputted while the standby mode enable signal is in the high state, when the active mode enable signal is in the high state.
