An auto-precharge control circuit is provided to generate auto precharge signal which is stable for PVT change by reducing a detail delay unit and the area of a chip. In an auto-precharge control circuit. A command decoder(100) generates active signal(ACT) according to the outer command(CLK, /RAS, /CAS, /WE). A bank enable signal generator(102) generates a bank enable signal(BANK(0:3)) according to an active signal. A sense amp enable signal generating unit(104) generates a sense amp enable signal according to the bank enable signal. A control signal generating part(106) generates a control signal(TRASMINDLY) for controlling the auto precharge operation according to the sense enable signal. |
