发明名称 Bipolar RAM cell
摘要 A memory cell is provided having reduced read and write times, and a large current differential between the standby mode and the read mode. A pair of cross-coupled NPN transistors have their emitters coupled to a lower word line and their collectors coupled to an upper word line by a first and second load, respectively. First and second NPN sense transistors each have a base coupled to the base of one of the cross-coupled transistors, an emitter coupled to a first and a second bit line, respectively, and a collector coupled to receive a supply voltage.
