IBM Unveils Memory Technology Breakthough
To read news article click on "IBM Unveils" above. Below see quote.
IBM is developing a new type of ultra-low-cost solid-state memory featuring a storage capacity that vastly exceeds what today's hard disk drives can provide. Called racetrack memory, the technology may one day replace hard disk drives in PCs, laptops and servers as well as displace flash memory chips in smartphones, digital cameras, and tablets.
The radically new type of storage memory is based on a breakthrough technology known as spintronics, which manipulates the two types of independent electrons found in electrical current -- called the "spin-up" and "spin-down" electrons. The goal is to enable computing devices to store bits of information by manipulating the magnetic state of a region within a nanowire that is just a few tens of nanometers wide.
A Year's Worth of Movies
Big Blue's goal is to boost device storage capacities by a factor of 100 times greater that what is currently available today from conventional memory devices. This would enable hardware makers to design portable gadgets capable of storing all the movies produced worldwide in a single year -- and with room to spare, IBM researchers said.
To make such memory densities possible, however, the domain walls of the nanowire racetrack must be manipulated at speeds of hundreds of miles per hour to atomically precise positions along the tracks. According to IBM researchers, the timescales in the tens of nanoseconds and the distances in micrometers are surprisingly long, given that research efforts over the past 50 years were unable to detect them.
"This was previously undiscovered in part because it was not clear whether the domain walls actually had mass, and how the effects of acceleration and deceleration could exactly compensate one another," Parkin said.
IBM researchers have just published their results in the Dec. 24 issue of Science. The paper by Luc Thomas, Rai Moriya, Charles Rettner, and Stuart Parkin of IBM Research is entitled, "Dynamics of magnetic domain walls under their own inertia." end quotes.

And this blog it is obvious that both on scientific, hard drive and gaming and smart phone and other levels we should expect a 100 fold increase in both Memory and speed of processing during the next 10 years on all new devices.
