Metal interconnect fuse memory arrays

A method for forming an integrated circuit, the method comprising:

• forming a metal interconnect above a substrate;
• forming a first contact above the metal interconnect and in contact with the metal interconnect;
• and
• forming a second contact above the metal interconnect and in contact with the metal interconnect, wherein a first resistance exists between the first contact and the second contact through the metal interconnect, and wherein a second resistance exists between the first contact, the metal interconnect, the second contact, and a non-conducting barrier as an interface between the second contact and the metal interconnect, the non-conducting barrier is formed after a programming voltage is applied to the second contact while the first contact is coupled to a ground terminal to generate a current between the first contact and the second contact.

A computing device, comprising:

• a circuit board;
• and
• a fuse memory array coupled to the circuit board, wherein the fuse memory array includes a plurality of fuse cells, a fuse cell of the plurality of fuse cells includes a fuse element coupled to a selector, and wherein the fuse element includes:
• a metal interconnect above a substrate;
• a first contact above the metal interconnect and in contact with the metal interconnect, wherein the first contact is coupled to a bit line of the fuse memory array;
• and
• a second contact above the metal interconnect and in contact with the metal interconnect, wherein the second contact is coupled to a first contact of the selector, and the selector includes a second contact coupled to a word line of the fuse memory array, a first resistance exists between the first contact and the second contact through the metal interconnect, and wherein a second resistance exists between the first contact, the metal interconnect, the second contact, and a non-conducting barrier as an interface between the second contact and the metal interconnect, the non-conducting barrier is formed after a programming voltage is applied to the second contact and the first contact is coupled to a ground terminal to generate a current between the first contact and the second contact.
