Abstract

An apparatus and a relative method which permit carrying out a complete cycle of functional tests and parametric measurements on EPROM type semiconductor devices during their permanence inside a burn-in chamber, thus greatly reducing the time necessary for testing and classifying the devices, besides ensuring a higher reliability. The system utilizes special "intelligent" cards, i.e., provided with a card microprocessor which may be connected to a supervisory system's CPU directing the test and classification process of the devices.
