Claim 3:
4. The internal voltage generation circuit of claim 1, wherein, in a second sub mode in the contact mode when a voltage level of the contact voltage is smaller than a first reference voltage and is greater than a second reference voltage,
the control signal generator is configured to disable the switched capacitor converter and the bidirectional switched capacitor converter, respectively, by using the first power-down signal and the second power-down signal, in response to the first mode signal and the second mode signal,
the first contact switch is configured to switch the contact voltage to the first node as the contact mode first driving voltage, and
the second contact switch is configured to switch the contact voltage to the second node as the contact mode second driving voltage.
