Voltage generation circuit and semiconductor circuit including the voltage generation circuit

A voltage generation circuit comprising:

• a driver configured to generate an internal voltage by driving an external voltage depending on a driving signal;
• a comparator configured to generate a comparison signal by comparing a reference voltage and a feedback voltage;
• a current mirror configured to generate the driving signal depending on the comparison signal;
• and
• a switch configured to delay a decrease of the internal voltage by precharging a node, coupled with a transistor for pulling down the driving signal in the current mirror, to a predetermined voltage, depending on a control signal.

A semiconductor circuit comprising:

• a voltage generation circuit comprising:
• a driver configured to generate an internal voltage by driving an external voltage depending on a driving signal;
• an amplifier configured to generate the driving signal depending on a result of comparing a reference voltage and a feedback voltage;
• a switch configured to delay a decrease of the internal voltage by precharging a node of the amplifier with a predetermined voltage depending on a control signal;
• a control signal generation circuit configured to generate one of a ground voltage and the external voltage, as the control signal, depending on setting information,
• wherein the setting information is changed in the content-addressable memory (CAM) read period of the semiconductor circuit.
