Rambus Demonstrates Superior Power Efficiency of World's Fastest Memory
* Fully Differential Memory Architecture (FDMA) - enhances signal integrity and increases performance through point-to-point differential signaling of clock, data, and command/address (C/A), an industry first;
* FlexLink C/A - reduces pin count and increases scalability; and
* Enhanced FlexPhase - enables the world's highest memory signaling rates while simplifying routing and board design.

In addition, the XDR2 memory architecture includes:

* Micro-threading of the DRAM core - introduced by Rambus in early 2005, increases data transfer efficiency and reduces power consumption; and
* 16X Data Rate - allows for extremely high data rates with the use of a relatively low-speed system clock.
