ABSTRACT:
The memory unit comprises a plurality of bipolar inverter transistors and an equal number of injector transistors, each of which acts as a current source for a different one of the inverter transistors. Means are provided for cross-coupling a first and a second of the inverter transistors to form a flip-flop. Third, fourth and fifth inverter transistors provide input data flow from the data line to the cross-coupled first and second inverters, in accordance with a write control sixth inverter transistor connected to receive a write signal. A seventh inverter transistor provides data output flow between the cross-coupled first and second inverter transistors and the data line in accordance with the read control eighth inverter transistor connected to receive a read signal.
