Description
Address inputs: Provide the row address for ACTIVE commands, and the column address
and auto precharge bit (A10) for READ/WRITE commands, to select one location out of the
memory array in the respective device bank. A10 sampled during a PRECHARGE command
determines whether the PRECHARGE applies to one device bank (A10 LOW, device bank
selected by BA0, BA1) or all device banks (A10 HIGH). The address inputs also provide the op-
code during a MODE REGISTER SET command. BA0 and BA1 define which mode register
(mode register or extended mode register) is loaded during the LOAD MODE REGISTER
command.
Bank address: BA0 and BA1 define the device bank to which an ACTIVE, READ, WRITE, or
PRECHARGE command is being applied.
Clock: CK, CK# are differential clock inputs. All address and control input signals are sampled
on the crossing of the positive edge of CK and the negative edge of CK#. Output data (DQ
and DQS) is referenced to the crossings of CK and CK#.
Clock enable: CKE (registered HIGH) activates and CKE (registered LOW) deactivates the
internal clock, input buffers, and output drivers.
Chip selects: S# enables (registered LOW) and disables (registered HIGH) the command
decoder.
Presence-detect address inputs: These pins are used to configure the presence-detect
device.
Serial clock for presence-detect: SCL is used to synchronize the presence-detect data
transfer to and from the module.
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.
Command inputs: RAS#, CAS#, and WE# (along with S#) define the command being
entered.
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.
Data input/output: Data bus.
Data strobe: Output with read data, input with write data. DQS is edge-aligned with read
data, center-aligned with write data. Used to capture data.
Power supply: +2.5V ±0.2V.
Serial EEPROM positive power supply: +2.3V to +3.6V.
SSTL_2 reference voltage (V
Ground.
No connect: These pins are not connected on the module.
No function: These pins are connected within the module but provide no functionality.
