  • Dual antifuse memory device
    Patent number: 5191550
    Abstract: A semiconductor memory device employing a plurality of antifuse memory elements is disclosed. The memory elements have selected connection portions of two or more elements formed as a unit and are otherwise electrically connected for use without regard to the polarity of the applied voltage. Such two-way antifuse memory elements formed in parallel become a unit thereby reducing occupied area and enhancing device integration.
