Ultra dense nanowire memory is possible Spanier as estimating the density of computer memory drives made of nanowires to be 10,000 terabits of data per cubic centimeter as opposed to the five gigabits per cubic centimeter of current flash memory drives. It's probably going to be fairly long before this can be achieved, however. Spanier predicts in the near future the development of new types of chemical sensors, emerging from the study of the interaction of a variety of molecules with nanoscaled ferroelectrics and ultra thin films.

Researchers at Drexel University and the University of Pennsylvania, both in Philadelphia, and Harvard University in Massachusetts, US, discovered that water turns barium titanate (BaTiO3) nanowires into a potential form of computer memory. The New Scientist magazine site was one of the first to discuss this development
