Nanowires could boost memory density |
Nanowires could boost memory density (Mar 15)
http://physicsweb.org/article/news/11/3/11
Physicists in the US have devised a new technique that brings us one
step closer to the possibility of using magnetic nanowires as
high-density data storage devices. The technique involves moving
magnetic domain walls -- the boundaries between regions of opposite
magnetization -- along a nanowire using a much smaller spin-polarized
current density than was possible before. The researchers claim that
this breakthrough could lead to a new type of magnetic memory with up to
100-times the storage density of existing random-access memories (RAMs)
(Science 315 1553).
