Successful DDR2 DesignSuccessful DDR2 Design Mentor Graphics highlights design issues and solutions for DDR2, the latest trend in memory design. by Steve McKinney HyperLynx Technical Marketing Engineer Mentor Graphics steven_mckinney@mentor.com The introduction of the first SDRAM interface, in 1997, marked the dawn of the high-speed memory interface age. Since then, designs have migrated through SDR (single data rate), DDR (double data rate), and now DDR2 memory interfaces to sustain increasing bandwidth needs in products such as graphics accelerators and high-speed routers. As a result of its highbandwidth capabilities, DDR and DDR2 technology is used in nearly every sector of the electronics design industry ……
