Abstract:
A latch circuit that latches stored data of a nonvolatile storage device used for setting the function of a semiconductor device and adjusting the characteristics of the semiconductor device required a dedicated input-output circuit for a test of the semiconductor device. By providing a dummy storage device, it becomes possible to perform a test of the semiconductor device without providing a dedicated input-output circuit.
