Original Abstract Submitted
A memory clock control circuit includes a voltage detection circuit and a first logic circuit. The voltage detection circuit receives a supply voltage of at least one memory, and outputs a control signal according to a comparison result of the supply voltage and at least one threshold value. The threshold value includes a first threshold value that is greater than a system reset voltage and less than a minimum operating voltage of the memory. The first logic circuit receives the control signal and a first clock signal of at least one memory controller, and outputs a first memory clock signal to the memory according to the control signal. According to the control signal, the first logic circuit outputs a clock stop signal to the memory when the supply voltage is less than the first threshold value. A method for controlling a memory clock is also provided.
