发明名称 IMPROVEMENTS IN WORD LINE DRIVER CIRCUIT IN MEMORY CIRCUIT
摘要 For driving a plurality of memory cells, a driver circuit, connected to the word driver line of the memory cells, includes a resistive connection, connected between the word line and ground potential, for preventing the potential of the word line from floating. The driver circuit includes an enhancement-type switching MOSFET and a depletion type resistor MOSFET connected in series. By virtue of the connection of a gate of the depletion type MOSFET, the depletion type MOSFET is always turned on so that whether or not the switching type enhancement MOSFET is turned on, the common connection between the switching MOSFET and the resistive MOSFET will always be at a prescribed potential thereby preventing the word driver line from floating.
