Abstract
A semiconductor device according to the present invention includes a plurality of test mode circuits. Each test mode circuit includes a plurality of decode circuits decoding an input signal and a plurality of latch circuits. Each decode circuit generates a test mode signal. The test mode signals are held in the latch circuits. Each test mode circuit further includes decode circuits outputting a group reset signal for resetting a corresponding latch circuit. Thus, a plurality of test mode signals can be combined arbitrarily and serially.
