IBM is currently developing a new form of digital storage that would increase both battery life and storage capacity up to ten times for handheld gadgets like the iPod and iPhone. This technology is said to be along the lines of NAND flash memory, only a bit faster and holds a longer expected lifespan.

Called as “Racetrack”, IBM says it “stores information inside the walls that exist between magnetic domains, such as those arrange on the surface of a silicon wafer”. As such, information flows around the columns at very high speeds compared to current storage mediums available in the market today.

IBM said, “The Racetrack could pave the way for devices such as digital media players that can




hold about a half million songs, cost far less to produce than today’s models and run on a single battery charge for weeks at a time”.

“The promise of racetrack memory - for example, the ability to carry massive amounts of information in your pocket - could unleash creativity leading to devices and applications that nobody has imagined yet,” added Stuart Parkin, the lead researcher for IBM.

According to Parkin, the racetack memory could allow the development of 3D microelectronics, making it one of the first technology to break away from “fitting a great number of transistors in 1 ultra-thin piece of wafer-shaped silicon.”
IBM expects the racetrack memory to benefit various electronic devices, including the iPhone, within the next ten years.
