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 Standard 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. User-specific information can be
written into the remaining 128 bytes of storage. System READ/WRITE operations
between the master (system logic) and the slave EEPROM device occur via a standard
I
which provide four unique DIMM/EEPROM addresses. Write protect (WP) is connected
to V
2
C bus using the DIMM’s SCL (clock) and SDA (data) signals, together with SA[1:0],
SS
, permanently disabling hardware write protect.
