US Patent 7272511 - DNA memory with carbon nanotube addressing

This patent from STMicroelectronics proposes a molecular memory using hybridization of DNA based using carbon nanotube addressing. Claim 1 reads:

1. A method for manufacturing a molecular memory device, comprising: forming an array of first nanoelectrodes on a substrate of insulating material; forming on said substrate a plurality of carbon nanotubes; functionalizing said nanotubes so that they are suitable for making contacts with DNA strands; contacting said first nanoelectrodes to first ends of the DNA strands; contacting said nanotubes to second ends of the DNA strands; hybridizing or not hybridizing said DNA strands to store desired data in the DNA strands.
