Software That Doubles Mobile Phone Memory

By Robert | September 30, 2007

A team of US computer scientists claim that they have found a way to double the usable memory of a mobile phone and different embedded systems with the use of software and no modification to applications or Hardware. This was tried a lot of times in the past but it was never used until now because of the huge battery drain that was noticed in the past. Things change as we know have CRAMES Technology (Compressed RAM for Embedded Systems), which uses Linux kernel swapping mechanism to realize which page to compress. Researchers claim that this technology does not use more battery power and the mobile phone only shows a performance loss that can be neglected. There is even a mobile phone being sold that uses CRAMES. That is NEC, but, as usually happens, it is only available in Japan at the moment.

There are a lot of compression algorithms used in different applications lately but it does seem like CRAMES appears with something truly efficient. There is an algorithm, called LZ0, which is used on NEC smartphones and uses CRAMES technology. Lei Yang developed another algorithm that is twice as fast when compared with LZ0 and makes negligible reduction in performance and battery life a reality. This might be included in future NEC smartphones.

The CRAMES technology really appears like something that could be very useful. Who knows, maybe it can also be used for giving the iPhone a 3G capability, although this is just a dream of mine. NEC could gain some sales with the implementation of this technology but it will be interesting to see when it will arrive to the USA and Europe. The Japanese market is filled with technology that appears there first, although the largest market is in America. We just need to get used to this!
