Nanotube chip could store data for a billion years 奈米管晶片能儲存資料10億年


Researchers have demonstrated a form of archive memory using carbon nanotubes that can theoretically store a trillion bits of data per square inch for a billion years.


The technology could easily be incorporated into today’s silicon processing systems and it could be available in the next two years, a lead researcher said.


The scientists at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory and the University of California said the new technology can potentially pack thousands of times more data into one square inch of space than today’s chips.


Researchers said this latest nanotube breakthrough uses an iron nanoparticle, approximately 1/50,000th the width of a human hair, that in the presence of a low voltage electrical current can be shuttled back and forth inside a hollow carbon nanotube with remarkable precision.


The shuttle’s position inside the tube can be read out directly via a simple measurement of electrical resistance, allowing the shuttle to function as a nonvolatile memory element with potentially hundreds of binary memory states.
