ABSTRACT:
Disclosed is a field effect transistor (FET) memory array in which each of the cells forming the array comprises four FET's. The first and second of the four FET devices are cross-coupled while the third and fourth FET devices form loads for the cross-coupled pair. D.C. stability is achieved by conditioning the load FET devices into partial conduction during the stand-by state of the memory cell.
