XDR™ Memory Architecture: The Picture-Perfect Solution for HDTV

iSuppli's latest consumer research finds that HDTV buyers' top priorities are Picture Quality followed by Price. These findings held true across nearly all income levels. The benefits of the XDR™ memory architecture are that it can help HDTV designers achieve the highest levels of performance while reducing silicon and system costs. Picture Quality, while subjective, is certainly driven by factors such as higher resolutions, increased color depth, higher frame rates and advanced motion compensation techniques. All of these require higher levels of memory bandwidth. The XDR memory architecture delivers the highest bandwidth per DRAM allowing designers to reach desired performance levels with the fewest number of devices.
XDR memory achieves its breakthrough bandwidth performance through high-speed differential signaling combined with key Rambus innovations such as FlexPhase™. But XDR memory also allows silicon and system designers to significantly reduce implementation and manufacturing costs. The robust high-speed signaling technology of XDR means that low-cost device packages can be used while still maintaining desired data rates and bandwidth. XDR memory's high-signaling speed requires fewer pins and reduced silicon area, and can be implemented with simpler and smaller PCB boards. In addition, inherent in differential signaling are lower EMI emissions and higher EMI immunity meaning that shielding can be reduced or even eliminated.
