Abstract

The invention provides a clear circuit of a memory; the clear circuit comprises a clear switch unit and a clear photoelectricity unit. The clear switch unit is coupled to a grounding terminal and a memory of a system chip, and is coupled to the clear photoelectricity unit. When the clear photoelectricity unit receives a clear line, a control signal is generated according to the clear line and is sent to the clear switch unit, then the clear switch unit is switched according to the control signal, and the memory of the system chip is coupled to the grounding terminal, thereby clearing the memory.

Description

Technical field [0001] The invention relates to a control circuit of an electronic device, in particular to a memory clearing circuit. Background technique [0002] In recent years, information technology and computer technology have continued to evolve, allowing computer systems to develop from servers to personal computers, and from desktop computers to portable computers (such as notebook computers). During the development and evolution of computer systems, computer systems need to perform boot procedures based on the system settings stored in the memory of the system chip in order to enter the operating system. However, when the computer system is abnormal, the boot procedure cannot be executed. At this time, the user will restart the computer system to eliminate the abnormality. Generally, the abnormality of the computer system is eliminated by turning on and off the power of the computer system, but when the user cannot eliminate the abnormality of the computer system by s...
