Abstract
An electronic device includes an internal voltage generation circuit configured to detect a voltage level of an internal voltage, that is generated by the internal voltage generation circuit. The internal voltage generating circuit is also configured to generate a drive code, which, along with a drive clock, determines the magnitude of the generated internal voltage. The drive code may be reset responsive to the internal voltage. The electronic device also includes a load circuit which is powered by the generated internal voltage.
