Abstract
An integrated circuit includes a set of non-volatile bits that may be programmed during multiprobe testing of the integrated circuit (IC). A defective portion of the IC is identified by testing the IC during multiprobe testing prior to packaging the IC. The IC is scrapped if the defective portion of IC does not meet repair criteria. A defect category is selected that is indicative of the defective portion, wherein the defect category is selected from a set of defect categories. The defective portion is replaced with a standby repair portion by modifying circuitry on the IC. The selected defect category is recorded in a plurality of non-volatile bits on the IC. The non-volatile bits may be read after extended testing or after end-user deployment in order to track failure rate of repaired ICs based on the defect category.
