Description
Serial data: Used to transfer addresses and data into and out of the SPD EEPROM on
the I
Redundant data strobe (x8 devices only): RDQS is enabled/disabled via the LOAD
MODE command to the extended mode register (EMR). When RDQS is enabled, RDQS
is output with read data only and is ignored during write data. When RDQS is disa-
bled, RDQS becomes data mask (see DMx). RDQS# is only used when RDQS is enabled
and differential data strobe mode is enabled.
Parity error output: Parity error found on the command and address bus.
Power supply: 1.8V ±0.1V. The component V
