Researchers at the University of Southern California and the NASA Ames Research Center have created a self-assembled molecular memory device they say has the potential of holding 40 Gigabits per square centimeter.
It achieves unprecedented compactness by using nanowires of indium oxide 10 nanometers in diameter and about 2000 nanometers long. It is still more compact because each memory cell can hold three bits of data, using 8 separate, stable identifiable electronic states.
