Abstract
According to the present invention, an intra-macro match determining circuitinternally determines whether or not n test outputs from each macro all have the same level. The result of the determination is combined with some of the test outputs, and the resultant signal is output to a tester. Thus, the determination result for a match is combined with the test outputs instead of a particular value. Consequently, the same expected value can also be used for individual macro testing, and output bits are assigned to each of the macros. Therefore, in internally performing a comparison with the expected value, the tester can easily detect defective macros.
