Boosting circuit and integrated circuit having the same

An integrated circuit comprising:

• a boosting circuit configured to generate a boosted voltage through an output node;
• and
• a control circuit configured to generate a control signal to control said boosting circuit,
• wherein said boosting circuit comprises:
• a power supply section comprising a first power supply configured to supply a first reference voltage and a second power supply configured to supply a second reference voltage;
• a boosting section configured to generate the boosted voltage in response to the first reference voltage and the second reference voltage;
• a comparator configured to compare the first reference voltage and the second reference voltage;
• and
• a switching circuit configured to control connection of an output node and said power supply section,
• wherein said comparator outputs a first comparison signal when the first reference voltage is higher than the second reference voltage and a second comparison signal when the second reference voltage is higher than the first reference voltage, and
• wherein said switching circuit connects said first power supply and said output node in response to the first comparison signal and connects said second power supply and said output node in response to the second comparison signal.
