  • Patent number: 8606102
    Abstract: A test interface device includes a serializer, an optical transmitter, an optical receiver, and a deserializer. The serializer receives parallel test signals from automatic test equipment, and serializes the parallel test signals into a serial test signal. The optical transmitter converts the serial test signal into an optical test signal. The optical receiver receives the optical test signal from the optical transmitter, and converts the optical test signal into the serial test signal. The deserializer deserializes the serial test signal into the parallel test signals, and transmits the parallel test signals to a device under test. As a result, signal transfer speed may be improved and optical resource usage may be reduced.

  • Patent number: 7973550
    Abstract: A semiconductor device test apparatus is provided. The semiconductor device test apparatus includes a test unit on which a semiconductor device under test is disposed, and an automatic test equipment (ATE) unit that inputs a test signal to the test unit and reads a test result signal output by the test unit. The semiconductor device test apparatus includes an interface unit that is interposed between the test unit and the ATE unit, and that compares the test signal with the test result signal and outputs to the ATE unit comparison signals indicating whether the semiconductor device is a failure or not or whether a specific bit failure has occurred or not.
