The
densest solid-state memory ever created could soon exceed the capabilities of
current computer storage devices by 1,000 times, thanks to a new technique
scientists at the University of Alberta have perfected."Essentially, you
can take all 45 million songs on iTunes and store them on the surface of one
quarter," said Roshan Achal, PhD student in Department of Physics and lead
author on the new research. "Five years ago, this wasn't even something we
thought possible."
His
team used the same technology they developed in previous research to build
atomic-scale circuits – which allows the quick removal or replacement of single
hydrogen atoms. This enables the memory to be rewritable, offering tremendous
potential for more efficient solid-state drives. Previous discoveries of
atomic-scale computer storage were stable only at extremely low temperatures.
But the new memory developed by Achal's team works at real-world temperatures
and can withstand normal use. The
technology has immediate applications for archiving data, according to Achal.
Next steps will include boosting the read and write speeds, for even more
flexible applications.
