Programmable nanocomputer to extend Moore's law - Smaller than a human nerve cell

An interdisciplinary team of scientists and engineers from The MITRE Corporation and Harvard University has taken key steps toward ultra-small electronic computer systems that push beyond the imminent end of Moore's Law, which states that the device density and overall processing power for computers will double every two to three years. In a paper that will appear this week in the Proceedings of the National Academy of Sciences, the team describes how they designed and assembled, from the bottom up, a functioning, ultra-tiny control computer that is the densest nanoelectronic system ever built.

The ultra-small, ultra-low-power control processor—termed a nanoelectronic finite-state machine or "nanoFSM"—is smaller than a human nerve cell. It is composed of hundreds of nanowire transistors, each of which is a switch about ten-thousand times thinner than a human hair.
