Single electrons perform logic The ultimate in transistors, which turn on and off in response to a flow of electricity, is a device that can be tripped by a single electron. Researchers from Hokkaido University have put together an AND logic circuit made from four single-electron tunneling transistors.   |

Magnetic memory makes logic Magnetic memory will soon put an end to the daily annoyance of waiting while your computer boots up from its hard disk. These chips that hold data when the power is off might also be capable of a lot more. Adding a few extra wires to each memory cell could turn the chips into efficient computer processors. |
