Abstract:
1. An anti-fuse type device for selectively providing an inverter that has an input connected to an input voltage that lies between an operating voltage supply (VDD) and ground, with a low resistance path to ground, the device comprising an irreversible snapback device having a gate or base control electrode formed between an anode and a cathode of the device, wherein the anode is connected to the operating voltage supply (VDD) through a resistor, the operating voltage supply (VDD) through the resistor being used both during programming of the device and during normal operation of the device after programming of the device, and the device being connected between the inverter input and ground, in which the gate or base control electrode of the device is connected during programming to a bias voltage higher than ground potential that is sufficiently high to cause the device to go into snapback mode.
