Methods, systems, and computer readable media for advanced power management for serial advanced technology attachment (SATA)-based storage devices

Abstract

Methods, systems, and non-transitory computer readable media for advanced power management for serial advanced technology attachment (SATA)-based storage devices are disclosed. According to one aspect, the subject matter described herein includes a method for advanced power management of SATA-based storage devices. The method includes, at a SATA-based storage device having a controller, a non-volatile memory for storing data, and a communication interface for communicating with a host, receiving from the host a command to enter a quiescent mode. In response to receiving the command to enter a quiescent mode, the storage device enters a quiescent mode. The storage device receives from the host an indication that the storage device should enter a low power mode. In response to this indication, the storage device puts at least a portion of the non-volatile memory into a low power mode while maintaining at least a portion of the controller in normal power mode. The storage device optionally puts a physical layer interface of the storage device into a low power mode for additional power savings.

Description

[0001] This application claims the benefit of US Provisional Patent Application Serial No. 13 / 040,519, filed March 4, 2011, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0002] The subject matter described herein relates to power management of memory devices. More specifically, the subject matter described herein relates to methods, systems, and computer-readable media for advanced power management of Serial Advanced Technology Attachment (SATA) based storage devices. Background technique [0003] Memory storage devices, data storage devices, memory devices, memories and storage devices are hereinafter referred to simply as "storage devices". Example storage devices include removable devices, such as memory cards, and non-removable devices, such as embedded memory. Embedded and removable devices attached to the host are powered on and use power even when they are not being accessed by the host. In some systems, such as camer...

Problems solved by technology

However, this method also has disadvantages

Although the PHY of the memory device may consume a certain amount of power, as the memory capacity within the memory device increases, the amount of power consumed by the memory becomes larger and larger
