DDR PHY Interface (DFI) Online

The DDR PHY Interface (DFI) specification is a collaborative industry effort to define a common interface between the DDR memory controller logic and the PHY interface in order to reduce cost, time-to-market, and increase the potential for reuse of the individual components that make up the memory system. The latest version of the DFI specification, 2.0 which is now available, has been developed by expert contributors from recognized leaders in the semiconductor, IP and electronic design automation (EDA) industries, including: ARM, Denali, Intel, LSI Logic, Samsung and ST Microelectronics. The DFI Specification Rev 1.0 was released for production development in January 2007 and has received an overwhelming response with over 1,000 users from 500+ companies downloading the specification. The current version of this industry standard DFI specification 2.0 is now available for download. More about DFI.
