Abstract
For example, to include plural data input/output terminals and a strobe terminal that are electrically connected in common by a test probe, a command address terminal that is connected to a test probe, and an output control circuit that performs a selecting operation of data output circuits based on a signal that is supplied to the command address terminal. According to the present invention, it is possible to perform a test that uses non-compressed actual data while allocating plural data input/output terminals to one determination circuit within a tester. With this configuration, it is possible to test a large number of semiconductor devices in parallel by using a limited number of determination circuits within the tester.
