Nanocomputer-like Memory Device

20 February 2007

Breakthrough research that can pave the way for Nanocomputer-like memory microprocessors is taking place at the University of California. Professor Qing Jiang of the school’s Bourns College of Engineering is designing the prototype for a switch-like device that is based on Nanotechnology. Specifically, the device would use carbon-based Nanotubes that can mimic the switching the functionality of silicon-based microprocessors.

To understand how such a device would work, think of a telescope with an outer and inner chamber to enable it to move its lenses back and forth. Professor’s Jiang’s device would consist of two Nanotubes that work in the same manner, one acting as the inner tube and the other as the outer tube, able to move back and forth as needed. This activity and movement of the Nanotubes would make it possible for them to represent one of three possible switching positions at any moment in time, using an electrostatic charge as the conduction path.

These devices offer significantly faster read and write times than the computer industry’s current flash drive offerings. The Nanotube-based design is significantly smaller than its flash based counterpart as well.

As reported earlier in this blog, the move towards Nanotechnology-based computer technology is moving at a breakneck pace, and this design by Professor Jiang is one more step in that direction. An article outlining his research is available online and can be read here.
