US Patent 7747546 - Nanotube spin memory

http://www.freepatentsonline.com/7747546.html

Isis Innovation has been established to help commercialize technologies developed from Oxford University. This recent patent teaches a spintronic-type memory structure based on fullerene molecules formed within a carbon nanotube. Claim 1 reads:

1. An information register comprising:

a substrate;

a nanotube provided on the substrate;

a plurality of units located within the nanotube, each of the units comprising an endohedral fullerene; and

a plurality of electrode gates provided on the substrate, wherein each of the units has a plurality of states useable for representing information, and wherein the plurality of information-representing states of each unit correspond to different spin states of the unit.
