Clock: CK and #CK are differential clock inputs. All addresses and control input
signals are sampled on the crossing of the positive edge of CK and negative
edge of #CK. Output data (DQs, DQS and #DQS) is referenced to the crossings
of CK and #CK.
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.
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
Masks write data when high, issued concurrently with input data.
Positive line of the differential data strobe for input and output data.
Negative line of the differential data strobe for input and output data.
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.
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.

DESCRIPTION
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)
