Embodiment Construction

[0015] like figure 1 As shown, it is a hardware architecture diagram of the first embodiment of the storage device power management system of the present invention. The storage device power management system 10 is applied to an electronic device 1, and the electronic device 1 may be a computer, a computer host, a server, a test machine, a notebook computer, a communication device, or the like. The electronic device 1 includes a plurality of storage devices 12, and the storage devices 12 may be hard disks, or other types of memory cards or storage devices. The storage device 12 is used to store various types of data, such as files, images and other information.

[0016] The storage device power management system 10 is used to manage and control the power supply of a plurality of storage devices 12 in the electronic device 1 . When the files stored in the storage device need to be accessed or perform related operations, the power of the corresponding storage device 12 is activ...

Abstract

The invention provides a system for power management of memory devices. The system is applied to an electronic device comprising a plurality of memory devices. The system comprises an index generation module for establishing file catalogue indexes of files in the memory devices, a power supply control module for turning off the power of the memory devices, a determination module for, upon receiving a user request for operating a file and when the file catalogue indexes include the information of the file, determining the memory device in which the file is saved, and a file management module for responding to the user request and operating the file, wherein the power supply control module is further used for turning on the power of the determined memory device and sending the user request to the determined memory device. The invention also provides a method for power management of memory devices. Due to the use of the system and the method, the power consumption of the memory devices can be reduced.

Description

technical field [0001] The present invention relates to power management technology, and in particular, to a storage device power management system and method. Background technique [0002] With the increasing amount of computing data or stored data, various electronic devices require more storage devices to store and back up data. Under normal circumstances, storage devices (such as hard disks, etc.) used for backup and archiving files are idle most of the time. This will inevitably cause these storage devices to idle for a long time, which not only affects the service life of the storage device. , is not conducive to energy saving and environmental protection. SUMMARY OF THE INVENTION [0003] In view of the above, it is necessary to provide a storage device power management system and method, which can turn off the power of the storage device that has been idle for a long time, and turn on the power of the corresponding storage device when a user request is received. ...
