Patent ID: 6936911

Claim:
A semiconductor integrated circuit device comprising: a semiconductor integrated circuit chip which comprises an internal circuit, a plurality of bonding pads having signal paths formed between themselves and the internal circuit, a switching circuit provided in a predetermined signal path so as to perform a switching operation to permit the internal circuit to be connected selectively to one of different bonding pads and form a single signal path therein, and means for feeding a switching signal to the switching circuit; a package enclosing the semiconductor integrated circuit chip and having a plurality of leads for connection to a printed circuit board; a plurality of conductors for connecting the bonding pads of the semiconductor integrated circuit chip to the leads of the package; and means for controlling the switching operation of the switching circuit in such a way that, when mutually adjacent conductors are arranged so close to each other that signals passing therethrough affect each other, a third conductor is used instead of one of said conductors so as to keep a distance from the other.
