IBM researchers in Zurich have demonstrated a single-molecule device that is capable of repeatedly storing and retrieving data.
The molecule is around 1.5 nanometers long, which is less than a hundredth of the size of existing silicon memory elements.
No commercial use for the device has so far been outlined by IBM. But it could be seen as a future replacement for silicon chip solutions, as the need for ever smaller transistor devices increases, to cope with the demand for greater computing power.

News of the device is published in the Small Times nanotechnology journal. The device is a simple organic compound which works to electrical pulses, and which can be repeatedly used in different states.
The BPDN-DT molecule system was designed by professor James Tour and colleagues at Rice University in Houston.
