A raised voltage generation circuit includes a charge pump circuit for outputting a first voltage, a voltage dividing circuit for receiving the first voltage and outputting second and third voltages, a first transistor for receiving the second voltage at a gate thereof, a second transistor for receiving the third voltage at a gate thereof, and a control circuit for controlling whether or not to operate the charge pump circuit. Currents of the same value flow through the first and second transistors when the first voltage is equal to a predetermined value, currents of different values flow through the first and second transistors when the first voltage is not equal to the predetermined value, and the control circuit controls whether or not to operate the charge pump circuit based on the currents that flow through the first and second transistors.
