ABSTRACT:
A bipolar memory array and memory cell. The memory cell has a pair of cross coupled NPN storage transistors and a pair of PNP load transistors. The collector of each of the load transistors is connected to one of the storage transistors. A base, common to both load transistors, are connected to a drain line. The word line is connected to an emitter common to both of the load transistors. The cell is connected to a bit line pair through Schottky Barrier Diodes (SBD's) or, alternatively, through emitters of transistors which share a common base and a common collector with the cross coupled storage transistors.
