Nanotech gets ready to take on transistors

This is where HP Labs and others get excited. Create two sets of parallel wires -- one running north-south, the other east-west -- and put roxatane molecules at each cross-over, and you have a memory architecture that can theoretically shrink much further than anything depending on transistors -- achieving a feature size of two to three nanometres. It should also be less power hungry and faster. The semiconductor physics underpinning transistor design has limits on how small voltages can be before they stop being effective: different and more advantageous rules apply for molecular switches.
