  • High density integrated logic circuit
    Patent number: 4129790
    Abstract: The disclosed logic circuit includes one transistor and a plurality of Schottky barrier diodes in each logic circuit "cell," a plurality of such cells being interconnected to perform desired logic functions. Cell interconnections are made by interconnecting metallurgy which can have a relatively high resistance with relatively long interconnecting paths between a sending circuit cell and a receiving circuit cell. The undesirable effects of this metallurgy resistance are overcome by driving the base of the receiving transistor through a base drive resistor in the sending cell.
