1. A method, comprising:

  • supplying a first power supply voltage for a charge pump circuit that generates a global body bias voltage;

    generating a local body bias voltage from the global body bias voltage;

    waiting for a predetermined delay after the local body bias voltage reaching and being stable at a predetermined value, and then supplying a second power supply voltage applied for transistors having the local body bias voltage while the local body bias voltage is stable at the predetermined value, the second power supply voltage being lower than the first power supply voltage.
