Abstract:
PURPOSE: A test interface device, a test system, and an optical interface memory device are provided to reduce the use of an optical resource using serialization and paralleling technology. CONSTITUTION: A first serializing unit(131) receives a parallel test signal from an automatic test device and serializes a parallel test signal into a serial test signal. A first optical transmitter(133) receives a serial test signal from the first serializing unit, converts the serial test signal into an optical test signal, and transmits the optical test signal. A first optical receiver(134) receives the optical test signal and converts the optical test signal into the serial test signal. A first paralleling unit receives the serial test signal from the first optical receiver, converts the serial test signal into the parallel test signal, and transmits the parallel test signal to a test target device.

Abstract:
PURPOSE: A built-off test device is provided to test a semiconductor device which is rapidly operated. CONSTITUTION: A frequency multiplying part(310) generates a test clock frequency by multiplying a clock frequency which is inputted from an external test device based on the operation speed of a semiconductor device. A command decoder(320) generates test information by decoding a test signal which is inputted from the external test device based on a test clock frequency. A test executing part(330) determines whether the semiconductor device is in an abnormal state from the test data outputted from the semiconductor device.
