Abstract
A signature circuit, i.e., a random-number generating circuit, is provided in a memory test apparatus. Also, a signature circuit is provided in each of devices-under-test. This configuration allows the large number of semiconductor integrated-circuit devices to be tested at one time with a high efficiency. This condition realizes a tremendous reduction in the test cost.
