Hardware and Layout Design Considerations for DDR2 SDRAM Memory Interfaces
by DSD Applications Freescale Semiconductor, Inc. Austin, TX
The design guidelines presented in this document apply to products that leverage the DDR2 SDRAM IP core, and they are based on a compilation of internal platforms designed by Freescale Semiconductor, Inc. The purpose of these guidelines is to minimize board-related issues across multiple memory topologies while allowing maximum flexibility for the board designer. Because numerous memory topologies and interface frequencies are possible on the DDR2 SDRAM interface, Freescale highly recommends that the system/board designer verify all design aspects (signal integrity, electri
