Abstract:
1. A system to sort integrated circuits (ICs) comprising: a plurality of integrated circuits (ICs); a tester machine configurable to test the plurality of ICs at a plurality of voltages and a plurality of frequencies, the tester machine to determine if each IC in the plurality of ICs is operable at a voltage and frequency combination within a predetermined set of voltage and frequency combinations based on repeated testing of an IC, wherein to fail operating within a voltage and frequency combination within the predetermined set at a given specification, the IC is to retest at a different combination of voltage and frequency within a different predetermined set of voltage and frequency combinations; a plurality of bins to receive from the tester machine ICs operable within the set of voltage and frequency combinations, wherein each bin is to receive ICs operable at a particular frequency; and a discard bin to receive from the tester machine ICs failing to operate at any voltage and frequency combination within any of the sets.
