Abstract
PURPOSE: To give interchangeability with a package without a scan path, and to make tests possible by using the scan path by providing a scan-path terminal to a side independent of a normal terminal, top surface or reverse surface.
CONSTITUTION: As for mounting, only normal input-output terminal 2 is used so as to maintain interchangeability with the same kind of a package as conventional one, and as to tests, terminal 3 is used for tests by the scan path. In a test time, terminal 3 is taken as a shift mode setting terminal, and data is scanned in and out by using terminal 2. Since the shift mode is exclusive with a normal mode, one terminal can be given different functions in the shift mode and in the normal mode. Terminal 2 assigned to the scan-in data input-output terminal is connected to both the scan path with its memory element consituted in the shift register and the normal internal circuit
