News: Sony, Toshiba Disclose PlayStation Chip Plans

At a joint press conference held in Tokyo today, Sony Corp. and Toshiba Corp. announced plans to build advanced semiconductor plants for the fabrication of faster and more complex chips as they look ahead to the next-generation PlayStation console and other broadband network products. Among the announcements include confirmation that the Cell processor will be the main engine behind the PlayStation 3.
The two companies each disclosed plans to build cutting-edge factories capable of handling 300-millimeter wafers at a production rule of 65 nanometers. The latter number refers to the smallest track or gap width on a chip's surface. Sixty-five nanometers is about a thousandth the width of a human hair, and about half the width that most of the world's most advanced semiconductor plants are capable of today. A smaller number means semiconductors can be made physically smaller, allowing for more processing power in the same amount of physical space.
The companies need such advanced production technology to produce the Cell microprocessor, which is being developed jointly by Toshiba, IBM Corp. and Sony Computer Entertainment Inc. (SCEI) to form the basis of the PlayStation 3 video gaming console and other future consumer electronics products. Although Sony confirmed that Cell will serve as the heart of the PS3, they declined to give a launch date for the new system, only stating that more details will be revealed at their next business-strategy conference.
The Cell chips are being developed as part of a five-year project that began in 2001 and has as its goal a 1 teraflop-class consumer microprocessor. If successful, the result would be a processor that could be fitted into household electronics, yet is more powerful than IBM's Deep Blue supercomputer. Sony plans to reveal its strategies for Cell's use this year, debuting appliances with the chip inside as early as next month.
Announcing its plans on Monday, Sony said it will spend 200 billion yen (about $1.7 billion) on the project over the next three years. Toshiba said it will spend a similar amount over the next four years in building 65-nanometer production lines. The Sony line will be constructed at the company's Nagasaki plant, while the Toshiba line will be at that company's Oita facility, both in Japan. Construction is planned to begin this June.
First-year investment from Sony will total 73 billion yen, while Toshiba said it plans to spend 40 billion yen this year on initial construction. Both companies declined to provide a schedule for trial or mass production on the chip lines.
The two companies also said that Sony is considering supporting Toshiba's investment in the new Oita line. However, a final decision on whether to provide funds to Toshiba and on how much to provide has yet to be made.
In a separate announcement, Sony also revealed Dragon, a new chip that combines the technology that drives the current PlayStation 2 into a single processor. Dragon is a one-chip version of the Emotion Engine and Graphics Synthesizer, the two CPUs that form the heart of the PS2, that takes up only a sixth of the physical size of the two chips. Sony did not announce what Dragon will be used for, but it's easy to imagine it utilized for PS3 backward compatibility or in a PS one-style redesigned PS2 system.
