Josephson junctions, with the barrier composed of a correlated metal (or insulator) tuned to lie close to the metal-insulator transition, show promise to provide the fastest operating speeds for digital electronics based on rapid single-flux quantum logic. We provide theoretical calculations that indicate that these devices have a small enough temperature derivative of I[sub c](T) within the junction operating range to allow them to be employed as elements in complex digital circuits.
