First Phase-Change Memory Cellphone
Samsung has just released the first Phase-Change memory smartphone on the mobile market. The coolest part is that it is an entry level model and it’s called the Samsung Monte GT-E2550. You can currently order the phone on Amazon’s UK website for just 40 pounds. A company called Chipworks that specializes in reverse engineering and semiconductor patents released a careful analysis of the phone.
If you’re unfamiliar with phase-change memory, it’s basically a special storage technology that combines the advantages of RAM with the non volatile aspects of flash memory. Last year, a 512Mbit manufactured version of the chip with a 65nm size was part of a multi-chip package last April.
Chipworks X-rayed the package to confirm that the chip on the Monte was a PCM one, they found that Samsung’s version has a similar architecture as a NAND flash device, which would mean large-scale production further in the future. Although another company called Numonyx released a 1GB 45nm chip in Dec of 2009, no products were ever made from the 45nm chip. HP labs has already been experimenting with data densities of more than 125GB per square inch. The technology is still relatively new so we won’t see too many phones with this technology for a while. Again, this is a basic phone, here are the tech specs from Amazon’s page:
