Data input/output: Bidirectional data bus.
Data strobe: Output with read data, input with write data for
source synchronous operation. Edge-aligned with read data,
center aligned with write data. DQS# is only used when
differential data strobe mode is enabled via the LOAD MODE
command.
Input data mask: DM is an input mask signal for write data. Input
data is masked when DM is sampled HIGH along with that input
data during a WRITE access. DM is sampled on both edges of
DQS. Although DM pins are input-only, the DM loading is
designed to match that of DQ and DQS pins. If RDQS is disabled,
DQS0–DQS17 become DM0–DM8 and DQS#9–DQS#17 are not
used (NC).
Redundant DQS: If RDQS is disabled, DQS0–DQS17 become DM0–
DM8 and DQS#9–DQS#17 are not used (NC).
Check bits.
Parity bit for the address and control bus.
Serial clock for presence-detect: SCL is used to synchronize the
presence-detect data transfer to and from the module.
Presence-Detect address inputs: These pins are used to configure
the presence-detect device.
Serial presence-detect data: SDA is a bidirectional pin used to
transfer addresses and data into and out of the presence-detect
portion of the module.
Asynchronously forces all registered outputs LOW when RESET#
is LOW. This signal can be used during power up to ensure that
CKE is LOW and DQs are High-Z.
