File Name: GDDR Memory Controller Interface Brief

Graphics and multimedia applications require high memory bandwidth to render life-like 3D images and buffer the large amount of frame data for image and video processing. In these applications, higher memory bandwidth translates directly into higher system performance, faster frame rates, and more features.

Graphics and multimedia logic chips need memory interfaces that deliver high bandwidth from a small number of components. These interfaces must often support not only highspeed specialty graphics DDR such as GDDR1/2/3, but also high-speed variants of main memory (DDR2). With current data rates of GDDR components exceeding 1GHz, memory interfaces for graphics and multimedia are challenging to design.

Rambus GDDR interface cells and services provide a comprehensive solution for high-bandwidth performance memory systems. With an emphasis on promoting customer success, Rambus DDR solutions include a family of interface cells, system and package design services, and bring-up support. Furthermore, Rambus GDDR solutions offer optional modes to higher performance levels.
