As Small As It Gets

IBM are hard at work as ever, attempting to create a toolkit of molecules that can be used as the components of logic and memory systems, in place of the semiconductor structures we use today. The search is going well, it seems – two researchers have announced that they have been able to use single molecules as a storage medium, by switching them between two discreet charged states. At 1.5 nanometers, the molecules are 1% of the size of CMOS structures that perform the same functions. Moore’s Law has held up well so far, but it will take developments like this for us to continue making smaller faster electronics.
