Rambus Unveils New Model to Monitor Energy Consumption in DRAM Devices

Applicable to all existing and emerging DRAM technologies

SUNNYVALE, Calif.-- December 7, 2010 -- Rambus Inc. (NASDAQ: RMBS), one of the world's premier technology licensing companies, is set to unveil a new power modeling tool designed to understand and predict energy consumption in current and future DRAM devices. This breakthrough model will be presented by Rambus' Dr. Thomas Vogelsang at the MICRO-43 conference in Atlanta, Georgia today at 1:30 pm ET.

"Power consumption is a serious challenge facing the DRAM industry. Historically, datasheets have been used to compute DRAM power, yet these tools have limited information with respect to future DRAM bandwidth requirements," said Dr. Gary Bronner, director of Rambus Labs. "This flexible power model is an industry first that allows engineers to extrapolate DRAM energy consumption to future DRAM generations."

During this presentation, Dr. Vogelsang will unveil this new flexible DRAM power model that can be used to calculate power usage. Attendees will hear how this model allows the calculation of DRAM power with an accuracy level between that of using datasheet values and full transistor level simulations.

Following MICRO-43, Dr. Vogelsang's presentation will be available at the Rambus media library: http://www.rambus.com/us/library/and the IEEE Xplore® digital library: http://ieeexplore.ieee.org/xpl/conferences.jsp
