Claims
- 1. An integrated circuit device comprising:
- a semiconductor substrate;
- a first plurality of well regions in said substrate of a first conductivity type, with each said well region having a respective probing pad;
- a second plurality of elongated regions of a second conductivity type in each said well region, with each said elongated region having at a first end thereof a contact in common with the first end of each of the others of said elongated regions,
- a third plurality of fuses, the number of said third plurality being the product of the numbers of said first and second pluralities, each said fuse being connected at a first end to the second end of a respective one of said elongated regions, and the other end of each said fuse being connected in common with the second end of the same corresponding one of said elongated regions in each said well region;
- a plurality of further probing pads, each connected to a respective one of the common connections of said second ends of the fuses, the number of said further probing pads being that of said second plurality.
- 2. The integrated circuit device of claim 1, wherein for np equal to the number of said probing pads and nf the number of said third plurality of fuses, the relation (np/2).sup.2 =nf obtains.
