Abstract: PURPOSE: To enable the self-inspection of an IC by simple constitution without generating circuit delay by using a three-state pass gate and a three-state receiver in combination with a linear feedback shift register(LFSR) and a memory register. CONSTITUTION: An LFSR 30 shifts the seed pattern of data successively to form a usual scanning data inspection pattern. When a self-inspection signal is set to a second state showing the inspection mode of an IC 10, the inspection pattern is scanned within a memory register 120 to be successively used in combination logic 125 and the inspection result thereof is stored in a fourth memory register 145. Next, when the signal 110 is reset to a second state, the operation of a three-state receiver 70 is stopped and, therefore, input boundary logic 20 inputs the inspection pattern scanned by a memory register 50 through a three-state pass gate 60 started in operation and an inspection result is stored in the register 120.
