ABSTRACT:
In an integrated circuit package, a ROM is provided for identifying the device for testing purposes. The ROM is programmed, for example, by cutting resistor links. The resistor links set the output of the PROM. This output is a binary word which is read by the tester at the same time that the tester performs measurements on the reference device. With this information the tester can then perform various calculations.
