Abstract:
A semiconductor device includes a digital circuit having a scan test mode. The digital circuit includes a first flip-flop forming a part of a scan chain when in the scan test mode, and a first selector provided on an input side of the first flip-flop. The first selector is capable of selecting a first signal when not in the scan test mode, and selecting a second signal that is different from the first signal when in the scan test mode.
