Abstract
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.
Claims14
An auto-precharge signal generation circuit comprising:
- a signal generator configured to generate a control signal and a precharge control signal in response to receiving a first column address strobe signal and an auto-precharge flag signal;
- a set signal generator configured to generate a set signal in response to receiving the control signal and the precharge control signal;
- and
- an auto-precharge signal generator configured to generate an auto-precharge signal in response to receiving the set signal and a period set signal,
- wherein the signal generator generates the control signal by delaying a signal, which is driven in a predetermined level from a time of enabling the first column address strobe signal and the auto-precharge flag signal until a time of enabling the set signal, in a predetermined period of an internal clock signal.
