  • Patent number: 11836358
    Abstract: A system comprises a power source and two power rails coupled to the power source. A storage device, comprising a non-volatile memory, a cache coupled to the non-volatile memory, and a control pin, is coupled to the second power rail. A power management controller is coupled to the first power rail and to a control pin of the storage device.
