Function
This bidirectional pin is used to transfer data into or out of the SPD EEPROM. A resistor
—
must be connected from the SDA bus line to VDDSPD on the system planar to act as a
pullup.
—
This signal is used to clock data into and out of the SPD EEPROM. A resistor may be con-
nected from the SCL bus time to VDDSPD on the system planar to act as a pullup.
Active Low
This signal indicates that a thermal event has been detected in the thermal sensing
device.The system should guarantee the electrical level requirement is met for the
EVENT pin on TS/SPD part.
No pull-up resister is provided on DIMM.
Serial EEPROM positive power supply wired to a separate power pin at the connector
which supports from 3.0 Volt to 3.6 Volt (nominal 3.3V) operation.
The RESET pin is connected to the RESET pin on the register and to the RESET pin on
the DRAM.
Used by memory bus analysis tools (unused (NC) on memory DIMMs)
