Abstract
Exclusive diode-FET logic circuitry capable of providing functional programmable logic array output logic signals within one-gate delay from an initial input logic signal, and functional read-only memory output data signals within two- or three-gate delay from an initial input address signal. The OR and AND functions of the circuit are performed by diode configurations thus resulting in high packing density, easy logic array programming, low power dissipation, and high speed operations. The invention may utilize Schottky diodes and metal semiconductor FETs thereby allowing the implementation of high speed gallium arsenide integrated circuit technology.
