  • Output circuit for driving a memory device output lead including a three-state inverting buffer and a transfer gate coupled between the buffer input lead and the buffer output lead
    Patent number: 4939392
    Abstract: A novel circuit is coupled to a memory device sense amplifier and a memory device output pin for driving the output pin with data. The circuit includes a first inverter (18) and a second inverter (100) coupled to the first inverter. Transfer gates (30, 104) are coupled across the input and output leads of the first and second inverters, respectively. During a first mode of operation, the first and second transfer gates are closed and the second inverter is three-stated so that the input and output leads of the first and second inverters are held at a voltage between VCC and ground. When it is desired to drive the memory device output pin with data, the first and second transfer gates open, and the second inverter leaves the three-state mode and goes into a low output impedance mode.
