Abstract
A protection circuit for a memory control chip of a computer includes a controller, a switch circuit, a memory control chip, and a delay circuit. The controller outputs a high level control signal when the computer is in a first state, and outputs a low level control signal when the computer is in a second state. The switch circuit connects or disconnects the connection between a power pin of the memory control chip and a power terminal, according to the control signal. The delay circuit imposes a predetermined time delay for receiving a high level control signal, and outputs an enable signal to an enable pin of the memory control chip to make the memory control chip operate again, after a predetermined delay.
