London, August 14 : German researchers have created a faster and more energy efficient version of the RAM used in computers today.

Santiago Serrano-Guisan and Hans Schumacher of the Physical-Technical Federal Laboratory of Germany have revealed that their version of RAM is about 10 times faster than the existing magnetoresistive random access memory (MRAM), which hardware companies think will in a few years dominate the market.

"Present MRAM are programmed by pulses of about 10 nanoseconds duration. So we are ten times faster," New Scientist magazine quoted Serrano-Guisan as saying.
