Globalfoundries teams up with Ayar Labs

Globalfoundries and Ayar Labs, a startup bringing optical input/output (I/O) to silicon chips, jave entered into a strategic collaboration to co-develop and commercialise differentiated silicon photonic technology solutions.

The companies will develop and manufacture Ayar’s novel CMOS optical I/O technology, using GF’s 45nm CMOS fabrication process, to deliver an alternative to copper I/O that offers up to 10x higher bandwidth and up to 5x lower power. This solution is integrated in-package with customer ASICs as a multi-chip module, and aims to improve data speed and energy efficiency in cloud servers, datacenters and supercomputers. As part of the agreement, GF has also invested an undisclosed amount in Ayar Labs. Modern data centers and cloud applications require high-performance, power-hungry chips to process and analyse huge volumes of data in real time. Growth in chip I/O capabilities has not matched exponential increases in computing power, because of physical limitations in electrical data transmission. Optical I/O, which leverages optical components on the CMOS die to transmit data at rapid speeds, will be a key enabler to overcoming the limitations of today’s data center interconnects. In addition, Ayar’s technology reduces power consumption at both the network and processor level, the companies state in a press release. “GF has demonstrated true technology leadership in recognizing optical I/O as the inevitable next step as we move into a More than Moore world,” said Alex Wright-Gladstein, CEO at Ayar Labs. “This collaboration between Ayar and GF could improve chip communication bandwidth by more than an order of magnitude and at lower power, and is a validation of Ayar’s viability in the current semiconductor ecosystem. This collaboration will unlock a larger market opportunity, expanding both our and GF’s customer base. We look forward to working with GF to help solve the interconnect problems of today’s chips and create greater value for our customers than if both companies worked independently.” “The Ayar Labs team has been designing cutting-edge silicon photonics components on GF’s technology for the past eight years and has achieved exceptional results,” said Mike Cadigan, senior vice president of global sales and business development at GF. “Our strategic collaboration builds on our relationship, leveraging GF’s silicon photonics IP portfolio and our world-class manufacturing expertise to enable faster and more energy-efficient computing systems for data centers.” The collaboration brings together Ayar Labs’ patented IP in optical technology with GF’s expertise in silicon photonics to co-develop optical solutions that will be fabricated using GF’s process technology.

The U.S. Department of Commerce announced on June 29 that the newly instituted Hong Kong national security law by the Chinese government will increase “the risk that sensitive U.S. technology will be diverted to [the Chinese government]”; the Department therefore put a temporary stop to the preferential treatment the U.S. had afforded to Hong Kong.

Arm is looking to strengthen its focus on growth and profitability. To achieve this the company has proposed strategic organisational changes – which involves the transferring of businesses.
