ABSTRACT:
A device for testing for disconnection of bus lines of a semiconductor device includes switches having current ratios formed in a geometric series connected to ends of a group of n of the bus lines. At least one testing electrode is connected to the switches and at least one power electrode is connected to the group of n of the bus lines. A disconnection of one or more of the bus lines can be determined according to a current flowing through the testing electrode.
