US Patent 7494842 - Programmable nanotube interconnect

This patent from LSI Corporation discloses using a nanotube interconnect to turn off an IC and save power. Claim 1 reads:

1. A method, comprising:

forming a interconnect layer using a plurality of nanotube structures; and

automatically altering a route of an integrated circuit based on an electrical current applied to at least one of the plurality of nanotube structures in the interconnect layer.

It is notable that Nantero has many earlier patents and publications which would seem to disclose this but which were not cited by the applicant or the patent office. One example is US Patent Application 2005/0280436.
