Filed: 1989-10-17
Abstract: PURPOSE:To easily execute the timing design of a sense enable signal generating circuit by generating a sense enable signal based on the boost signal of a word line boosting circuit equipped with timing close to sense. CONSTITUTION:A timing circuit TIM outputs 0 while being delayed by the sum of the delay time of delay circuits DL1 and DL2 after a row address decod er latches and decodes an address. At such a time, a potential VWSL of a word line source WSL in a word line boosting circuit BST rises up to a VCC at a prescribed time constant. Next, after the lapse of the delay time of delay circuits DL3 and DL4, an output voltage VD4 of the circuit DL4 starts rising up and the potential VWSL of the WSL as the sum of the VCC and a VD is increased with the prescribed time constant. Thus, a sense amplifier SA of a dynamic memory cell array MCA is controlled. An NAN2 of a CSN outputs 0 while being delayed for a certain time and the output is sufficient as the sense enable signal. Thus, the signal is outputted at timing after turning ON an MOSFET Qij and connecting a capacitor Cij to a bit line.
