Abstract
A memory power supply backup system aims to activate and switch a power supply backup system, to provide electric power to a memory, temporarily storing data when the power supply is interrupted abnormally to avoid losing data in the memory. When the power supply is back to normal, the computer system restores to the condition prior to the power supply interruption according to the data temporarily stored in the memory, to continue the unfinished process, thereby to enhance the reliability and stability of the computer system.
