    摘要: An auto-precharge signal generation circuit comprises a signal generator, a set signal generator, and an auto-precharge signal generator. The signal generator is configured to generating a control signal and a precharge control signal in response to receiving a first column address strobe signal and an auto-precharge flag signal. The set signal generator is configured to generating a set signal in response to receiving the control signal and the precharge control signal. The auto-precharge signal generator is configured to generate an auto-precharge signal in response to receiving the set signal and a period set signal.
