... DRAM is connected to a single trace and terminated (rather than a tree structure, where the termination is off the module near the connector). Inherent to fly-by topology, the timing skew between the clock and DQS signals can be easily accounted for by using the write-leveling feature of DDR3 ...

... Serial Presence-Detect EEPROM Operation DDR3 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 comply with JEDEC specification JC-45 “Appendix X: Serial Presence Detect (SPD) for DDR3 SDRAM Modules” (pending approval). These bytes identify module-specific timing parameters, configuration information, and physical attributes ...

... Electrical Specifications Stresses greater than those listed in Table 6 may cause permanent damage to the module. This is a stress rating only, and functional operation of the module at these or any other conditions outside those indicated in each device’s data sheet is not implied. Exposure to absolute maximum rating conditions for extended periods may adversely affect reliability ...

... Micron encourages designers to simulate the signal characteristics of the system’s memory bus to ensure adequate signal integrity of the entire memory system. Power Operating voltages are specified at the DRAM, not at the edge connector of the module. Designers must account for any system voltage drops at anticipated power levels to ensure the required supply voltage is maintained. ...
