Abstract
A programmable interconnect structure and method of operating the same provides a programmable interconnection between electrical contacts. The interconnect includes material that has a reversibly programmable resistance. The material includes a molecular matrix with ionic complexes distributed through the molecular matrix. Application of an electrical field or electric current causes the molecular composite material to assume a desired resistivity (or conductivity) state. This state is retained by the molecular composite material to thus form a conductive or a non-conductive path between the electrical contacts.
Claims42
A semiconductor device comprising:
- a first electrical contact;
- a second electrical contact;
- and
- an interconnect between the first and second electrical contacts, the interconnect having a reversibly programmable resistance.
A programmable interconnect structure, comprising:
- first and second electrical contacts;
- and
- an interconnect between the first and second electrical contacts and comprising a material that has a reversibly programmable resistivity, the material comprising a molecular matrix.
A method of electrically connecting and disconnecting electrical contacts in a circuit by programming of an electrical interconnect between the electrical contacts, comprising the steps of:
- selectively applying a first electrical field or first current to the electrical interconnect to program the electrical interconnect to assume a first state of conductivity to electrically connect the electrical contacts through the electrical interconnect;
- and
- selectively applying a second electrical field or second current to the electrical interconnect to program the electrical interconnect to assume a second state of conductivity to electrically isolate the electrical contacts through the electrical interconnect;
- wherein the electrical interconnect comprises a material that has a reversibly programmable conductivity, the material comprising a molecular matrix.
