Classification: CPC H  G | IPC G  H

Claim 10:
11. A memory module comprising:
a power management integrated circuit supplied by a first power source and a second power source and configured to output a bias voltage output, the power management integrated circuit comprising:
a charge pump supplied by the second power source and configured to generate a charge pump voltage output, the bias voltage output of the power management integrated circuit being generated based at least in part on the charge pump voltage output, the charge pump being configured to adjust the charge pump voltage output based at least in part on a comparison between the bias voltage output and a reference voltage; and
a self-biased switch disposed between the output of the charge pump and the output of the voltage regulator, the self-biased switch being configured to switch between outputting the charge pump voltage output and having a high output impedance.
