SUNNYVALE, Calif. -- January 28, 2013

Rambus Inc. (NASDAQ: RMBS), the innovative technology solutions company that
brings invention to market, today announced its first LPDDR3 offering targeted
at the mobile industry. In the Rambus R+ solution set, the R+ LPDDR3 memory
architecture is fully compatible with industry standards while providing
improved power and performance. This allows customers to differentiate their
products in a cost-effective manner with improved time-to-market. Further
helping improve design and development cycles, the R+ LPDDR3 is also available
with Rambus’ collaborative design and integration services.

The R+ LPDDR3 architecture includes both a controller and a DRAM interface and
can reduce active memory system power by up to 25% and supports data rates of
up to 3200 megabits per second (Mbps), which is double the performance of
existing LPDDR3 technologies. These improvements to power efficiency and
performance enable longer battery life and enhanced mobile device
functionality for streaming HD video, gaming and data-intensive apps.

“Each generation of mobile devices demands even higher performance with lower
power. The R+ LPDDR3 technology enables the mobile market to use our
controller and DRAM solutions to provide unprecedented levels of performance,
with a significant power savings,” said Kevin Donnelly, senior vice president
and general manager of the Memory and Interface Division at Rambus. “Since
this technology is a part of our R+ platform, beyond the improvements in power
and performance, we’re also maintaining compatibility with today’s standards
to ensure our customers have all the benefits of the Rambus’ superior
technology with reduced adoption risk.”

The seed to the improved power and performance offered by the R+ LPDDR3
architecture is a low-swing implementation of the Rambus Near Ground Signaling
technology. Essentially, this single-ended, ground-terminated signaling
technology allows devices to achieve higher data rates with significantly
reduced IO power. The R+ LPDDR3 architecture is built from ground up to be
backward compatible with LPDDR3 supporting same protocol, power states and
existing package definitions and system environments.

Additional key features of the R+ LPDDR3 include:

  *1600 to 3200Mbps data rates
  *Multi-modal support for LPDDR2, LPDDR3 and R+ LPDDR3
  *DFI 3.1 and JEDEC LPDDR3 standards compliant
  *Supports package-on-package and discrete packaging types
  *Includes LabStation™ software environment for bring-up, characterization,
    and validation in end-user application
  *Silicon proven design in GLOBALFOUNDRIES 28nm-SLP process

The R+ LPDDR3 memory controller and DRAM interface solutions are currently
available. For additional information on the Rambus R+ LPDDR3, visit
