Title: Precharging circuit
Inventor: MORITA TAKASHI
IPC: G11C11/41
Filed: 1988-10-13
Abstract: PURPOSE:To perform the self-control of the precharging time and to avoid the collision against an address control signal by using a circuit which controls the gate signal of an FET of a precharging circuit with use of the voltage information on a 1st bit line and a gate control signal. CONSTITUTION:The Nch FET 1 - 3 are connected to a gate control circuit 4 as prescribed. When a gate control signal line 6 is kept at 'L', the output of the circuit 4 is set at 'L' with all FETs turned off. When the line 6 is kept at 'H', all FETs are turned on to precharge the 1st and 2nd bit lines 9 and 10. When the precharge voltage drops by one stage of the FET gate, the voltage information is inputted to the circuit 4 through a feedback line 5. Thus the circuit 4 drops its output to 'L' despite the input of a control signal and turns off each FET. The threshold voltage VT and the length and the width of a gate of each FET are changed for selection of the precharge voltage level and the precharging speed. In such a constitution, the precharging time can be self-controlled and therefore the collision is avoided between the gate and address control signals.
