With a new memory introduced to the smart phones now they can read and write faster data with and their battery life can be improved up to 20%. In a new innovation, Samsung has recently announced that it produces memory module developed of phase change material. These modules are made up of substances that record or erase data when it is heated and typically use far less power than existing equivalents. These modules would start production in later half of 2010. Samsung plans to produce phase change memory (PCM) chips in the same format as existing designs so they can easily be worked into production runs.

The most common form of PCM is generally made up of an alloy of germanium, antimony and titanium that constitutes a glass-like material. When it is heated by applying a voltage it turns the material into two different separate forms that shows up variable and different resistances to electricity. So the material can be used to show up binary 0s and 1s that are used and employed by computers. As Samsung’s plan to produce PCM modules 512megabits in size it announced it at mobile technology forum held in Taipei.

These will be made to be compatible with traditional flash memory modules that have individual components only 40 nanometres wide. In addition, it said, PCM had a simpler structure than older formats so it should be easy to manufacture and start using in phones. Samsung lab tests suggest that the 512Mbit phase change memory can read and write data up to 10 times faster than some existing flash memory types. Overall, said Samsung, phase change memory is about three times faster than existing flash memory.
