Claim 12:
13. A method comprising:
providing a storage device power status to a host device using a unidirectional power state hardware pin of a storage device, separate from a communication interface between the host device and the storage device, the unidirectional power state hardware pin controlled by the storage device;
automatically, while the communication interface is disabled by the host device and after a threshold amount of time after completing an operation without receiving or performing a subsequent command or operation, moving, using the control circuitry, host data stored in volatile memory of the storage device to non-volatile memory of the storage device, wherein the volatile memory of the storage device is separate from host memory of the host device; and
automatically transitioning the storage device power status on the unidirectional power state hardware pin the from an active power status to a low power status after automatically moving the host data stored in volatile memory of the storage device to non-volatile memory of the storage device, indicating that the host device can remove VCC from the storage system.
