ABSTRACT:
Method and apparatus for regulating an antifuse programming current by lightly doping an electrically connected region so that the resistance of the region responds in a non-linear manner to changes in voltage. In this way a variable resistor or a variably resistive transistor may be created which vary their resistance in response to an applied voltage and which may thereby limit a programming current while not limiting a lesser, reading current to a serially connected antifuse.
