  • Patent number: 6118294
    Abstract: The invention is an integrated circuit testing device for testing whether a plurality of unknown data stored in a device under test are identical. A test pattern generated by a pattern generator 1 is supplied to a device under test 5 through drivers 3, as a result of which unknown data 5-1 obtained from the device under test 5 are sent through a comparator 4 and a judgment circuit 6 to be stored in an expected value memory 7 as a dummy expected value pattern. Thereafter, further unknown data 5-2, 5-3, . . . are sequentially read from the device under test 5 to collate them with the unknown data 5-1 in the expected value memory 7 by means of the judgment circuit 6.
