Patent ID: 7763812

Claim:
A semiconductor device comprising: a substrate; a first internal terminal, a second internal terminal, a third internal terminal, and a fourth internal terminal which are placed along perimeter of the substrate; a circuit formed on the substrate and coupled to the first internal terminal; a first external terminal coupled to the second internal terminal; a second external terminal coupled to the third internal terminal; and a third external terminal coupled to the fourth internal terminal and placed beside one side of the substrate where the second external terminal is located, wherein the circuit outputs a signal indicative of a connection state between the first internal terminal and the first external terminal, wherein a distance between centers of the first internal terminal and the second internal terminal is L 1 in a direction parallel to one side of the substrate beside which the first external terminal is placed, wherein a distance between centers of the third internal terminal and the fourth internal terminal is L 2 in a direction parallel to the one side of the substrate beside which the second external terminal and the third external terminal are placed, and wherein the distance L 1 is smaller than the distance L 2 .
