... 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) ...

... 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 ...
