Positive line of the differential pair of system clock inputs that drives
input to the on-DIMM PLL.
Negative line of the differential pair of system clock inputs that drives
the input to the on-DIMM PLL.
CKE HIGH activates, and CKE LOW deactivates internal clock signals,
and device input buffers and output drivers of the SDRAMs. Taking
CKE LOW provides PRECHARGE POWER-DOWN and SELF
REFRESH operation (all banks idle), or ACTIVE POWER DOWN (row
ACTIVE in any bank)
Enables the associated SDRAM command decoder when low and
disables decoder when high. When decoder is disabled, new
commands are ignored and previous operations continue. These input
signals also disable all outputs (except CKE and ODT) of the register(s)
on the DIMM when both inputs are high. When both S[0:1] are high, all
register outputs (except CKE, ODT and Chip select) remain in the
previous state. For modules supporting 4 ranks, S[2:3] operate similarly
to S[0:1] for a second set of register outputs.
On-Die Termination control signals
CAS, WE When sampled at the positive rising edge of the clock, /CAS,
/RAS, and /WE define the operation to be executed by the SDRAM.
Reference voltage for SSTL18 inputs
Isolated power supply for the DDR SDRAM output buffers to provide
improved noise immunity
Selects which SDRAM bank of four or eight is activated.
During a Bank Activate command cycle, Address defines the row
address. During a Read or Write command cycle, Address defines the
column address. In addition to the column address, AP is used to
invoke autoprecharge operation at the end of the burst read or write
cycle. If AP is high, autoprecharge is selected and BA0, BA1, BA2
defines the bank to be precharged. If AP is low, autoprecharge is
disabled. During a Precharge command cycle, AP is used in
conjunction with BA0, BA1,BA2 to control which bank(s) to precharge. If
AP is high, all banks will be precharged regardless of the state of BA0
or BA1 or BA2. If AP is low, BA0 and BA1 and BA2 are used to define
which bank to precharge.
Data and Check Bit Input/Output pins
Power and ground for the DDR SDRAM input buffers and core logic.
Positive line of the differential data strobe for input and output data.

Negative line of the differential data strobe for input and output data. If
RDQS is enabled, /DQS9 ~ /DQS17 are used only during READ
command
These signals are tied at the system planar to either VSS or VDDSPD
to configure the serial SPD EEPROM address range.
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 connected from the SCL bus time to VDDSPD on the
system planar to act as a pullup.
Serial EEPROM positive power supply (wired to a separate power pin
at the connector which supports from 1.7 Volt to 3.6 Volt (nominal 1.8
Volt, 2.5 Volt and 3.3 Volt) operations.
The RESET pin is connected to the RST pin on the register and to the
OE pin on the PLL. When low, all register outputs will be driven low and
the PLL clocks to the DRAMs and register(s) will be set to low level (the
PLL will remain synchronized with the input clock)
