Apparatus and method to provide near zero power DEVSLP in SATA drives
Abstract:
Apparatus and methods of reducing power consumption in solid-state disks (SSDs) that can reduce power levels in SSDs below levels achievable in known SSD reduced power states. The apparatus is a power management subsystem operative to detect whether an SSD subsystem has been enabled to enter a reduced power state, and to receive a control signal from a host directing the power management subsystem to place the SSD subsystem in the reduced power state. In the event the SSD subsystem is enabled to enter the reduced power state and the host asserts the control signal, the power management subsystem effectively disconnects at least a portion of the SSD subsystem from the power rail. In the event power-up clear circuitry asserts a clear signal to the power management subsystem, or the host negates the control signal, the power management subsystem reestablishes the connection between the SSD subsystem and the power rail.
