Abstract
A test signal supplying apparatus for a semiconductor device testing apparatus that tests a plurality of semiconductor devices; including: a test pattern generating unit for outputting an input signal pattern to the semiconductor devices and receiving a match signal which indicates the semiconductor device, to which the input signal pattern is applied, is passed in the test; and a match-fail detecting unit for receiving the match signal to detect a semiconductor device that fails in the test and outputting a match-fail signal for identifying the semiconductor device that fails in the test; and a stop signal output unit connected to the match-fail detecting unit for receiving the match-fail signal from the match-fail detecting unit, storing the match-fail signal, and outputting a first stop signal that stops an application of the input signal pattern to the semiconductor devices that fail in the test identified by the stored match-fail signal.
