Rambus and GLOBALFOUNDRIES Demonstrate Outstanding Performance and Power Results in 28nm Silicon Test Chips

SUNNYVALE, CALIFORNIA, UNITED STATES and MILPITAS, CALIFORNIA, UNITED STATES – 07/24/2012 – Rambus Inc. (Nasdaq:RMBS) and GLOBALFOUNDRIES today announced the results from their collaboration on two separate memory architecture-based silicon test chips. The first test chip demonstrates solutions for mobile memory applications, such as smartphones and tablets. The second test chip demonstrates solutions for compute main memory applications, such as servers. Using GLOBALFOUNDRIES’ 28-nanometer super low power (28nm-SLP) process, and demonstrating the capabilities of one of the most power efficient and highest performance analog/mixed-signal offerings for advanced system-on-chip (SoC) developments, the results of the two test chips have surpassed power and performance expectations.

“The partnership with GLOBALFOUNDRIES is vital to our ongoing commitment to innovation that advances the leading edge of electronics performance,” said Sharon Holt, senior vice president and general manager of the Semiconductor Business Group at Rambus. “GLOBALFOUNDRIES’ 28nm-SLP process is ideal for achieving multi-gigahertz data rates at unmatched power efficiencies.”

“Our 28nm-SLP technology gives SoC designers a robust manufacturing option for a new generation of feature-rich consumer and mobile devices, and assures optimal power consumption that is critical for success in these markets,” said Mojy Chian, senior vice president of Design Enablement at GLOBALFOUNDRIES. “We are pleased to be working closely with Rambus to demonstrate the capabilities and design enablement ecosystem available for the industry’s most cost-effective and versatile 28SLP process.”

Rambus’ mobile and server memory architectures are designed to meet the growing performance demands of future systems driven by applications such as 3D gaming, HD video streaming, capture and encoding, while providing unmatched power efficiency. With the rising popularity of streaming video, smartphones, tablets, and other smart mobile devices, there is a growing need for next-generation dynamic random access memory (DRAM) technologies capable of delivering the bandwidth necessary to power devices with the latest feature sets.

GLOBALFOUNDRIES’ 28nm-SLP technology is designed specifically for the next generation of smart mobile devices, enabling designs with faster processing speeds, smaller feature sizes, lower standby power and longer battery life. The technology is based on bulk silicon CMOS substrates and utilizes the same “Gate First” approach to High-k Metal Gate (HKMG) that has reached volume production in GLOBALFOUNDRIES Fab 1 in Dresden, Germany.

Over the past two years, Rambus and GLOBALFOUNDRIES have collaborated on a number of 28nm-SLP test chips covering core Rambus memory architectures for both mobile and server-based applications. The test chips leverage the wide range of design enablement support and solutions GLOBALFOUNDRIES offers, including process design kits (PDKs), extensive implementation services, and its DRC+™ design-for-manufacturing technology. Previously, Rambus has also used the GLOBALFOUNDRIES assembly support team to provide wirebond and flipchip packaging options on high-speed PHY designs.

More information on Rambus’ design implementation using the GLOBALFOUNDRIES 28nm-SLP process can be found in the companies’ 28nm collaboration white paper at: http://globalfoundries.com/eBooks/white%20papers/GF_Rambus_WhitePaper.aspx

This technology initiative includes the development of new memory signaling innovations that will facilitate blazing fast data rates of 16Gbps and enable a future memory architecture that can deliver an unprecedented terabyte per second (TB/s) of memory bandwidth (1 terabyte = 1,024 gigabytes) to a single System-on-Chip (SoC). With the technology developed through this initiative, Rambus will dramatically increase the data rate of memory above the current world’s fastest memory, the Rambus 4.8GHz XDR™ DRAM. Rambus will demonstrate a silicon test vehicle for its Terabyte Bandwidth Initiative today at RDF-Japan.

“We will drive memory signaling technology to performance levels that are an order of magnitude greater than what can be achieved today,” said Kevin Donnelly, senior vice president of engineering at Rambus Inc. “Continuing the Rambus tradition of innovation, our engineers and scientists have pioneered new technologies that will enable terabyte per second memory architectures for gaming, computing and consumer electronic systems of the next decade.”

Rambus’ Terabyte Bandwidth Initiative includes ground-breaking innovations for a new generation of memory systems, such as:

  • 32X data rate – 32 data bits per input clock cycle;
  • Fully Differential Memory Architecture (FDMA) – The industry’s first differential signaling for both data and command/address (C/A);
  • FlexLink™ C/A – The industry’s first full-speed, point-to-point C/A link.

The Terabyte Bandwidth Initiative is the latest in a long tradition of pioneering Rambus technology development programs. For more than seventeen years, Rambus engineering teams have developed the leadership innovations that enable faster signaling and advanced system designs. Committed to the advanced research and development of high-speed memory architectures, Rambus invests heavily in advanced circuit design, high-speed logic interfaces, low-power interface solutions, system engineering, signal integrity, verification, and testing. To date, Rambus engineers and scientists have developed innovations resulting in over 1000 issued and pending patents worldwide.
