Abstract
An embodiment is a method and apparatus to save data during power failure. A power supply generator generates operating voltages to a circuit from a generator supply source. A power monitor monitors a normal supply voltage and a backup supply voltage to provide a normal supply voltage to the generator supply source in a normal mode and to provide a backup supply voltage to the generator supply source in a power failure mode. A data transfer circuit transfers data from a volatile memory in the circuit to a non-volatile memory during the power failure mode.
