Rev. B 06/09
The temperature from the integrated thermal sensor is monitored and converts into a
digital word via the I
to create a custom temperature-sensing solution based on system requirements. Pro-
gramming and configuration details comply with JEDEC standard No. 21-C page 4.7-1
“Definition of the TSE2002av, Serial Presence Detect with Temperature Sensor.”
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 JE-
DEC standard JC-45 “Appendix X: Serial Presence Detect (SPD) for DDR3 SDRAM
Modules.” These bytes identify module-specific timing parameters, configuration infor-
mation, and physical attributes. User-specific information can be written into the
remaining 128 bytes of storage. READ/WRITE operations between the system (master)
and the EEPROM (slave) device occur via an I
Vss, permanently disabling hardware write protect. For further information please refer
to Micron technical note TN-04-42, "Memory Module Serial Presence-Detect."
