Phase change memory from Numonyx within sight

Numonyx Phase Change Memory (PCM) could be coming yet this yearAccording to an announcement by Numonyx CEO Brian Harrison, the company is expecting to have phase change memory (PCM) commercially available and start shipping this year. PCM is a new type of memory that would be in competition with Flash memory and has been in the works for decades but has yet to see commercialization.

Numonyx is a joint venture between STMicroelectronics and Intel and appears to be the first to announce a real-sounding time line for this type of memory. A number of companies have been working on phase change memory including an announcement from IBM in late 2006. Harrison says they are shipping samples now and will have the new memory widely commercially available in the next year or two.

Smaller, Faster Non-Volatile Memory From IBM

Phase Change Memory that could replace Flash memory chipsToday scientists from IBM, Macronix and Qimonda unveiled a new type of memory with the intention of possibly being a replacement for flash memory which is used in many electronic gadgets today.

The new memory announced today is called “phase-changememory. The memory would have the same applications as flash memory, but with a a couple key advantages. First of all, the phase-change memory has shown to be faster than flash memory; up to 500 times faster. It would also only consume about half the power that flash memory does, even with the greater speed. Secondly, the phase-change memory is smaller. A cross section of the new memory prototype measures only 3 x 20 nanometers.

“These results dramatically demonstrate that phase-change memory has a very bright future,” said Dr. T. C. Chen, Vice President, Science & Technology, IBM Research. …
