... LOW), where the input signals pass through the register/buffer to the SDRAM devices on the same clock. A phase-lock loop (PLL) on the modules is used to redrive the clock signals to the SDRAM devices to minimize system clock loading (CK0 is connected to the PLL, and CK1, CK2, and CK3 are terminated) ...

... Serial Presence-Detect Operation SDRAM modules incorporate serial presence-detect. The SPD function is implemented using a 2,048-bit EEPROM. This nonvolatile storage device contains 256 bytes. The first 128 bytes are programmed by Micron to identify the module type and various SDRAM organizations and timing parameters. The remaining 128 bytes of storage are available for use by the customer ...

... Ambient operating temperature (commercial) OPR Design Considerations 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 ...
