Abstract
PURPOSE: To make it possible to form on the same substrate hysteresis registers corresponding to FFs by constituting respective terminals on the same substrate including a test-result output terminal where a signal obtained from final-stage FF in a group of FF is outputted.
CONSTITUTION: External input terminals 12...18 receive external signals and then store them in one FF7. A signal from this FF7 is outputted from normal output terminals 19 and 20 and clock input terminal 18 receives an external arrival clock signal. Further, FFs 8...11, connected so that sequential shifts are made in response to a clock from terminal 18 on reception of a signal from FF7, are constituted on the same substrate including a test-result output terminal where a signal obtained from final-stage FF11 among FFs 8...11 is outputted. Consequently, hysteresis registers corresponding to FFs can be formed on the same substrate without increasing external terminals in number.
