Abstract
Method and apparatus are disclosed for checking the resistance of antifuse elements in an integrated circuit. A voltage based on the resistance of an antifuse element is compared to a voltage based on a known resistance, and an output signal is generated whose binary value indicates whether the resistance of the antifuse element is higher or lower than the known value of resistance. The method and apparatus are useful in verifying the programming of antifuse elements.
