Integrated circuit device with functions selectable by changing interconnection pattern

A semiconductor device comprising:

• first and second power supply interconnection patterns to which predetermined electric potentials are to be applied, respectively;
• an internal circuit for selecting functions of the semiconductor device or inhibiting use of a circuit of the semiconductor device;
• and
• an internal circuit interconnection pattern connected to said internal circuit, wherein
• both of said first and second power supply interconnection patterns have interconnection connecting portions which are adjacent a predetermined portion of said internal circuit interconnection pattern and separated therefrom by predetermined spaces smaller than a diameter of a bonding wire for connecting the first and second power supply interconnection patterns to a power supply lead.
