  • Patent number: 4297721
    Abstract: A MOSFET random access memory having an extremely low current load memory cell is disclosed. The memory cell comprises a cross-coupled binary stage in which one or more paths to ground can be selectively switched on or off through true and complement data nodes. Impedance means connect a power supply node to the data nodes for charging the data nodes to predetermined voltage levels. The impedance means comprise an intrinsic-extrinsic junction of a substantially pure, intrinsic semiconductor material and a diffusion of extrinsic conductivity impurities disposed within a region of the intrinsic semiconductor material. The impedance means is formed by an isoplanar silicon gate process as an integral portion of a polycrystalline silicon strip which interconnects the power supply node to a data node. A portion of the polycrystalline silicon strip is extended from the data node to form the gate of the transistor to which it is cross-coupled.
