IBM, Infineon, Macronix team on phase-change memory

IBM, Infineon and Macronix have agreed to work together to investigate phase-change memory (PCM), Macronix said.

PCM is long-researched form of memory stores data by reversibly changing the state of a material from an amorphous to a crystalline structure. With the potential to story data when power is removed the technology could be a long-term rival to flash memory, although lengthy research at numerous sites over several decades has yet to produce a commercial phase-change memory.

The research work is set to be conducted at IBM's TJ Watson Research Center in Yorktown Heights, New York, and the IBM Almaden Research Lab in San Jose, California. Approximately 20 to 25 employees from across the three companies are to be dedicated to this project, Macronix said.

Macronix did not give a timetable for expected progress. Nor did the Macronix say which material system the team would be researching.

One year ago STMicroelectronics said it was entering a productizing stage with its phase-change memory based on a chalcogenide materials system.

"We believe our collective dedication on PCM will help to not only extend the non-volatile memory roadmap beyond the current floating gate, and the 2bits/cell NBit technologies but also open new market opportunities," said Miin Wu, president and chief executive officer of Macronix International Co. Ltd. (Hsinchu, Taiwan).
