DDR2 SDRAM

Micron's DDR2 can boost designs with greater clock frequency and available bandwidth without increasing power consumption.

DDR2 is the next step to higher performance DDR technology.  Micron's DDR2 can boost designs with greater clock frequency and available bandwidth without increasing power consumption.  For more information, please see   Migrating from DDR to DDR2 Design Resources For a technical overview of DDR2 components, including new signaling features such as On-Die Termination (ODT), please see Micron's DesignLine article: DDR2 Offers New Features and Functionality .
