1. A semiconductor apparatus comprising:
a power supply pin configured to receive a power supply voltage from an outside;
a capacitor connection pin to be connected with a capacitor;
a power supply circuit having an input connected to the power supply pin and having an output connected to the capacitor connection pin, the power supply circuit being configured to generate an internal power supply voltage at the output of the power supply circuit;
a nonvolatile memory configured to operate by receiving the internal power supply voltage;
a switch disposed between a power supply terminal of the nonvolatile memory and the capacitor connection pin; and
a control unit configured to turn on the switch when the internal power supply voltage exceeds a predetermined threshold value.
