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. The remaining 128 bytes of storage are available for use
by the customer. System READ/WRITE operations between the master (system logic)
and the slave EEPROM device occur via a standard I
(clock) SDA (data), and SA (address) pins. Write protect (WP) is connected to V
nently disabling hardware write protection. For further information refer to Micron
technical note TN-04-42, "Memory Module Serial Presence-Detect."
