  • High conductance circuit for programmable integrated circuit
    Patent number: 4609998
    Abstract: A unique programming circuit, suitable for use with programmable read-only memories (PROM), or other circuits utilizing programmable fuses, is provided which overcomes several distinct disadvantages of prior art programming circuits. The programming circuit of this invention includes a Darlington pair of programming transistors which allows only a single programming transistor to be made large in order to carry the large programming current, and only a single high current drive signal need be applied to the single programming transistor, thereby minimizing power consumption and integrated circuit die area.
