Antimony and Tellurium Phase Change Memory to Replace Silicon Memory. New Material to Replace Conventional Memory

9:01 pm | Yaroslav Lyssenko

While the industry is continuing to develop more and more sophisticated technologies for future DRAM and other types of conventional data storage, the research of much more technically advanced ways of storing data takes place. It was recently discovered that phase change memory technique, that works similar with CDs and DVDs, could be used to replace DRAM, flash memory and even hard disk drives if it proves to be successful.

“Researchers at Royal Philips Electronics say they have devised a material that could replace existing types of computer memory through a technique that has been studied for years. The material, a thin layer of antimony and tellurium, could be used to create phase change memory, which largely works the same way CD and DVD discs do. A laser is directed to a microscopic point on a layer of the material to obtain a reflection. The reflection will differ, depending on whether the molecules at that particular point are amorphous or arranged in a crystal. The two types of reflections then become the ones and zeros of data,” writes CNET News.com

Intel's Pentium M Fights Against Desktop Champs Again. Intel’s Pentium M 735 Processor and DFI 855GME Mainboard Reviewed

Hexus.net has posted an interesting article about Intel Pentium M microprocessor powered desktop system. DFI 855GME mainboard along with Intel Pentium M 735 microprocessor was compared  against typical high-end desktop solutions form Intel and AMD in a set of tests. The benchmarks’ results showed an interesting picture concerning mobile processor’s performance.

“Performance wise, there’s one thing that stands out from the analysis and observation of P-M’s scaling with nothing more than its base frequency: it's crying out for core logic to let it breathe and perform to its fullest; there’s definitely plenty of extra performance to be had by pairing P-M with Alviso core logic. There’s also extra performance to be had just by upping the CPU’s bus clock, so the upcoming 200MHz Pentium-Ms, using Alviso, should give very fine performance, comparatively,” claims Hexus.net.
