Patent 7237158 was granted and assigned to Micron Technology on June, 2007 by the United States Patent and Trademark Office.
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 are 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.
