Abstract
A built off testing apparatus coupled between a semiconductor device and an external testing apparatus to test a semiconductor device. The built off testing apparatus can include a frequency multiplying unit to generate a test clock frequency by multiplying the frequency of a clock input by the external testing apparatus according to the operation speed of the semiconductor device, an instruction decoding unit to generate test information by decoding test signals input by the external testing apparatus according to the test clock frequency, and a test execution unit to test the semiconductor device according to the test information, and can determine whether the semiconductor device is failed or not based on test data output by the semiconductor device, and can transmit resulting data to the external testing apparatus.
