ABSTRACT:
A circuit for controlling precharge in a semiconductor memory apparatus includes a read clock driver configured to drive an internal clock signal and generate a read burst clock signal; a read precharge control unit configured to generate a read auto precharge signal in response to the read burst clock signal, a burst end signal, and a read write mode signal; a write clock driver configured to drive the internal clock signal and generate a write burst clock signal in response to the read write mode signal and a data input off signal; a write precharge control unit configured to generate a write auto precharge signal in response to the write burst clock signal, the burst end signal, a write latency signal, and a write address combination signal; and a precharge signal generation unit configured to combine the read and write auto precharge signals and generate an auto precharge signal.
