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. The power management controller stops the provision of power via the first power rail and provides a signal to the storage device via the control pin when the provision of power via the first power rail is stopped. The storage device continues to receive power from the second power rail when the provision of power via the first power rail is stopped. The storage device stores data from the cache to the non-volatile memory in response to the receipt of the signal via the control pin.
