摘要： The present invention relates to a system and method for testing one or more semiconductor devices (e.g., packaged chips). Test equipment performs at least tests of a first type on the semiconductor device and identifies failures in the semiconductor device, if any. A number of failures is determined. In the case where there are some failures, decision circuitry determines whether it is more efficient to repeat the tests or repair the semiconductor device, if it is repairable. The semiconductor device may be binned differently depending on the number of identified failures. The decision circuitry may designate the semiconductor device for an additional procedure, if the number of the identified failures is within a first number set. The decision circuitry may designate the semiconductor device for repair, if the number of the identified failures is within a second number set. The decision circuitry designate the semiconductor device for additional tests of the first type, if the number of the identified failures is within a third number set. The tests of a first type may be a hot sort procedure and the additional tests may be a cold final procedure.

摘要： 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.

摘要： 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.
