This patent from Nantero has priority going back to 2001 and is basic to the use of nanotube fabric in electronic structures such as memory and logic arrays. Claim 1 reads:

1. A structure, comprising:

a substrate having a surface, the substrate comprising patterned regions of conductor and patterned regions of insulator below the surface of the substrate; and

a nonwoven nanotube fabric of unaligned nanotubes disposed on the surface of the substrate, wherein the nonwoven nanotube fabric is parallel to the substrate.
