ABSTRACT:
Disclosed is a memory cell circuit including a pair of memory transistors having respective collectors and bases cross-coupled to each other, wherein load means connected to the collector of each one of said memory transistors comprises a parallel circuit of a load resistance and a transistor whose emitter and collector are connected to both ends of the load resistance and whose base is connected to the collector of the other of the memory transistors, thereby causing the readout currents of the memory cell circuit to be greater irrespective of increased load resistances.
