  • High-speed bipolar memory system
    Patent number: 5029129
    Abstract: A switched load diode cell has been developed wherein first and second multi-emitter NPN transistors are provided having bases cross coupled to the other's collectors in typical latch fashion as shown in FIG. 5. A PN diode is provided having an anode coupled to the select line through a load resistor and a cathode coupled to the collector of each associated multi-emitter transistor. A parasitic lateral PNP transistor associated with the PN diode is provided having an emitter coupled to the select line through the same load resistor and a collector connected to the base of the associated multi-emitter transistor. A relatively low resistance load of about 500.OMEGA. is connected between the common node which consists of the emitter of the parasitic lateral PNP transistor and the anode of the PN diode and the select line. In this way, a switched load diode cell is provided.
