  • Single element security fusible link
    Patent number: 5309394
    Abstract: An I/O circuit including first and second I/O pads, a fuse connected between the first pad and a RAM write enable line, and a diode-connected transistor connected between the RAM write enable line and second pad. Data is written to the RAM by applying a voltage potential to the pads after which the fuse is blown by increasing the potential difference. Other forms of the invention include a resistor connected between the RAM write enable line and ground, and I/O lines connected between the pads, respectively, and a logic circuit.
