Computer memory works on the basis of electrons that are moved around and stored. Electrons are small and, when it comes to insuring that information will not be lost over time, can be difficult to control using relatively thick insulator walls, so that information will not be lost over time. The physics issues limit storage density and cost the system a great deal of energy so researchers pursue nanoelectronic components that make use of ions, i.e. charged atoms, for storing data. Ions are some thousands of times heavier that electrons and are therefore much easier to 'hold down'. In this way, the individual storage elements can almost be reduced to atomic dimensions, which enormously improves the storage density. read more
