Description
SDA
I/O
Serial data: Used to transfer addresses and data into and out of the temperature sen-
sor/SPD EEPROM on the I2C bus.
TDQSx,
TDQSx#
Output
Redundant data strobe (x8 devices only): TDQS is enabled/disabled via the LOAD
MODE command to the extended mode register (EMR). When TDQS is enabled, DM is
disabled and TDQS and TDQS# provide termination resistance; otherwise, TDQS# are
no function.
Err_Out#
EVENT#
VDD
Output
(open drain)
Parity error output: Parity error found on the command and address bus.
Output
Temperature event: The EVENT# pin is asserted by the temperature sensor when crit-
(open drain) ical temperature thresholds have been exceeded.
Supply
Power supply: 1.35V (1.283–1.45V) backward-compatible to 1.5V (1.425–1.575V). The
component VDD and VDDQ are connected to the module VDD
