ABSTRACT:
Read signals to be outputted in the unit of bits from a packaged RAM are received to produce complementary output signals, and these output signals and the non-inverted and inverted signals of expected values are individually inputted to two logic circuits, so that the outputs of the logic circuits are compared by a coincidence/incoincidence circuit to produce a decision output.
