APPARATUS FOR SYNCHRONIZING MEMORY TEST BOARD

摘要

PURPOSE: An apparatus for synchronizing memory test board is provided to perform the synchronization of the test board. CONSTITUTION: The apparatus for synchronizing memory test board includes the first line, the second line and the comparison unit(120). The first line is connected to the output terminal of the test elements. The second line is connected to the output terminal of the test elements in parallel with the first line. The comparison unit is outputted from two test elements selected out of a plurality of the test elements. The comparison unit receives the test signal through the first line or the second line. The comparison unit compares the time delay difference of the inputted test signal.
