IBM Announces Phase Change Memory- 100x More Efficient

IBM announced today a special breakthrough in computer memory tech that may lead to solid state drives being able to store as much as NAND flash technology but work at a speed of 100x faster than current clock speeds, and have a much longer lifespan.

The technology is based on phase-change memory chips that store two bits of data per cell, forgoing corruption problems (a previous setback in PCM technology).

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.
