... JEDEC clock reference board. Registered mode will add one clock cycle to CL. Serial Presence-Detect Operation DDR SDRAM modules incorporate serial presence-detect. The SPD data is stored in a 256-byte EEPROM. The first 128 bytes are programmed by Micron to identify the module type and various DDR SDRAM organizations and timing parameters. The remaining 128 bytes of storage are available for use by the customer ...

... Design Considerations Simulations Micron memory modules are designed to optimize signal integrity through carefully designed terminations, controlled board impedances, routing topologies, trace length matching, and decoupling. However, good signal integrity starts at the system level. Micron encourages designers to simulate the signal characteristics of the system’s memory bus to ensure adequate signal integrity of the entire memory system ...
