Introduction
-
The Key to Smaller, More Powerful Gadgets
- September 2008 Scientific American articlette,
subtitled "Current ways of storing information on PCs and
cell phones won't cut it as memory demands grow and devices shrink."
-
More Bits in Pits
- February 2005 Scientific American In Depth article, subtitled
"DVD-like system could take a run at holographic storage".
-
Non-Volatile Magnetic Random Access Memory
- Brief overview of IBM research on magneto-electronic
memory devices.
-
The "millipede" project
- Information on an IBM research project for a "nanomechanical
AFM-based data storage system".
(AFM = "antiferromagnetic".)
-
Magnetoelectronics enhance memory
- Summary of December 2003 article from
Physics World, by
Daniel Hagele and Michael Oestreich.
"The logical units in conventional computer processors are
hard-wired to perform different tasks, which means that each
unit requires its own set of logic gates comprising even more
transistors. Now, Klaus Ploog and co-workers at the Paul Drude
Institute for Solid State Electronics in Berlin have proposed
an exciting way to use MRAMs to perform logic operations that
could lead to increased computational efficiency and reduction
in chip size."
-
A new spin on magnets
- February 2001 news article from
Physicsweb, about
a possible new amd faster technique for magnetic recording.
-
Optical data storage enters a new dimension
- July 2000 article from
Physics World.
"Holographic data storage promises increased storage densities
and improved access times that could lead to a new range of
novel memory devices."
-
Magnetic media: faster and smaller
- October 2000 news article from
Physics World.
-
Magnetic recording sets speed record
- October 1999 news article from
Physics World
about a faster way to access magneticly recorded data.
-
Magnetoelectronics
- Summary of April 1999 article in
Physics World, by
Jo de Boeck and Gustaaf Borghs.
"New microelectronic components that exploit the spin, rather
than the charge, of the electron are being designed by the
semiconductor and magnetic-recording industries."
-
Racetrack Memory: The Future Third Dimension of Data Storage
Stuart S. P. Parkin
Scientific American, June 2009
- "A device that slides magnetic bits back and forth along
nanowire "racetracks" could pack data in a three-dimensional
microchip and may replace nearly all forms of conventional
data storage."
