Abstract

A fuse corner pad is part of an integrated circuit that includes a built-in fuse contact and a plurality of auxiliary pads. The fuse contact is a conductive metallic or metalloid structure that is connected to a fuse element. The fuse contact and fuse element are used inside of the fuse corner pad for programmability (e.g., for security) and/or adjustment (e.g., trimming) of analog and/or digital signals. The fuse contact and fuse element are not required to be bonded to an external electrical connection (such as, a pin or ball). The auxiliary pads provide a variety of functional or non-functional applications, such as testing, probing, programming, and/or circuit adjustment.

Claims (25)

1. An integrated circuit, comprising:

a fuse corner pad having first and second edges that define a corner of said integrated circuit, said fuse corner pad including a fuse contact connected to a fuse element, wherein both said fuse contact and said fuse element are integrated within the boundaries of said fuse corner pad;

wherein said fuse corner pad is one of a plurality of fuse corner pads, wherein each fuse corner pad in said plurality of fuse corner pads is located at a respective corner of a semiconductor die,

wherein said fuse corner pad is configured to adjust said integrated circuit.

2. The integrated circuit of claim 1 , wherein said integrated circuit is coupled to a printed circuit board.

3. The integrated circuit of claim 1 , wherein blowing said fuse element performs said adjusting.

4. The integrated circuit of claim 1 , wherein not blowing said fuse element performs said adjusting.

5. An Ethernet device including the integrated circuit of claim 1 .

6. The integrated circuit of claim 1 , wherein the fuse corner pad is coupled to a logic control circuit.

7. The integrated circuit of claim 1 , wherein blowing said fuse element performs said identifying.

8. The integrated circuit of claim 1 , wherein not blowing said fuse element performs said identifying.

9. The integrated circuit of claim 1 , wherein said adjusting assigns an identification number to said integrated circuit.

10. An Ethernet device including the integrated circuit of claim 1 .

11. An Ethernet device including the integrated circuit of claim 1 .

12. An integrated circuit, comprising:

a fuse corner pad having first and second edges that define a corner of said integrated circuit, said fuse corner pad including a fuse contact connected to a fuse element, wherein both said fuse contact and said fuse element are integrated within the boundaries of said fuse corner pad;

wherein said fuse corner pad is one of a plurality of fuse corner pads, wherein each fuse corner pad in said plurality of fuse corner pads is located at a respective corner of a semiconductor die,

wherein said fuse corner pad is configured to identify said integrated circuit.

13. An integrated circuit, comprising:

a fuse corner pad having first and second edges that define a corner of said integrated circuit, including:

a fuse element connected to a fuse contact; and

a conductive path coupled to said fuse element,

wherein said fuse element is configured to protect said conductive path from a current that exceeds a predetermined threshold and said fuse corner pad is one of a plurality of fuse corner pads, wherein each fuse corner pad in said plurality of fuse corner pads is located at a respective corner of a semiconductor die; and

a plurality of auxiliary pads disposed on said integrated circuit

wherein said fuse contact, fuse element, and auxiliary pads are all integrated within the boundaries of said fuse corner pad.
