Abstract
Method and apparatus are disclosed for checking the resistance of programmable circuits in an integrated circuit where each programmable circuit includes a programmable element, such as an antifuse. A precharged node is connected to the programmable element and the voltage at the node discharges based on the resistance of the programmable element. An output signal is produced whose binary value is based on the voltage at the node after a sufficient time has elapsed to allow the initial voltage to discharge based on the resistance of the programmable element.
