Title:
SEMICONDUCTOR STORAGE DEVICE-BASED DATA RESTORATION
Document Type and Number:
WIPO Patent Application WO/2013/015561
Kind Code:
A1
Abstract:
Embodiments of the invention provide a device and method for warm booting whereby data restoration occurs at the powering-on of the host, and can therefore be performed by the boot disk. Specifically, when the system is powered on, a backup controller will send a notification to a DMA controller indicating the data restoration is needed. The backup controller will automatically resorts contents of a backup storage device to main memory. During the process, when the host requests data, the DMA controller reads the data from the backup storage unit and sends it to the host. Then, once data restoration is complete, normal operations can commence.
