A report at the DailyTech covers new work at the University of Pennsylvania’s School of Engineering and Applied Science using nanowires for storage. The nut
One way to further increase density could be to add a third state, or a 2. UPenn’s nanowire storage medium does just that.
…In addition to a third readable state, UPenn’s nanowires have other properties which make them ideal for volatile memory storage. Due to the third state itself, densities become much greater. This could either enable smaller memory devices for portable electronics, or much more storage in current form factors.
