Description
NT1GC64B88A0NF and NT2GC64B8HA0NF are 240-Pin Double Data Rate 3 (DDR3) Synchronous DRAM Unbuffered Dual In-Line
Memory Module (UDIMM), organized as one rank of 128Mx64 (1GB) and two ranks of 256Mx64 (2GB) high-speed memory array. Modules
use eight 128Mx8 (1GB) 78-ball BGA packaged devices and sixteen 128Mx8 (2GB) 78-ball BGA packaged devices. These DIMMs are
manufactured using raw cards developed for broad industry use as reference designs. The use of these common design files minimizes
electrical variation between suppliers. All NANYA DDR3 SDRAM DIMMs provide a high-performance, flexible 8-byte interface in a 5.25”
long space-saving footprint.
The DIMM is intended for use in applications operating of 533MHz/667MHz clock speeds and achieves high-speed data transfer rates of
1066Mbps/1333Mbps. Prior to any access operation, the device
latency and burst/length/operation type must be programmed into the
DIMM by address inputs A0-A13 and I/O inputs BA0~BA2 using the mode register set cycle.
The DIMM uses serial presence-detect implemented via a serial EEPROM using a standard IIC protocol. The first 128 bytes of SPD data
are programmed and locked during module assembly. The remaining 128 bytes are available for use by the customer.

The system clock inputs. All address and command lines are sampled on the cross point of the
rising edge of CK and falling edge of
.
A Delay Locked Loop (DLL) circuit is driven from the
clock inputs and output timing for read operations is synchronized to the input clock.
Activates the DDR3 SDRAM CK signal when high and deactivates the CK signal when low. By
deactivating the clocks, CKE low initiates the Power Down mode or the Self Refresh mode.
Enables the associated DDR3 SDRAM command decoder when low and disables the command
decoder when high. When the command decoder is disabled, new commands are ignored but
previous operations continue, Rank 0 is selected by

define the operation to be executed by the SDRAM.
Asserts on-die termination for DQ, DM, DQS, and
signals if enabled via the DDR3 SDRAM
mode register.
The data write masks, associated with one data byte. In Write mode, DM operates as a byte mask
by allowing input data to be written if it is low but blocks the write operation if it is high. In Read
mode, DM lines have no effect.
The data strobes, associated with one data byte, sourced with data transfers. In Write mode, the
data strobe is sourced by the controller and is centered in the data window. In Read mode, the
data strobe is sourced by the DDR3 SDRAM and is sent at the leading edge of the data window.
signals are complements, and timing is relative to the cross point of respective DQS and
.
If the module is to be operated in single ended strobe mode, all
signals must be tied on
the system board to V
SS
and DDR3 SDRAM mode registers programmed appropriately.
Selects which DDR3 SDRAM internal bank of four or eight is activated.
During a Bank Activate command cycle, defines the row address when sampled at the cross point
of the rising edge of CK and falling edge of
.
During a Read or Write command cycle, defines
the column address when sampled at the cross point of the rising edge of CK and falling edge of
.
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-BAn 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-BAn to control which bank(s) to precharge. If AP is
high, all banks will be precharged regardless of the state of BA0-BAn inputs. If AP is low, then
BA0-BAn are used to define which bank to precharge.
Data Input/Output pins.
Power supplies for core, I/O, Serial Presence Detect, Temp sensor, and ground for the module.
Reference voltage for SSTL15 inputs
This is a bidirectional pin used to transfer data into or out of the SPD EEPROM and temp sensor.
A resistor must be connected from the SDA bus line to V

on the system planar to act as a pull

This signal is used to clock data into and out of the SPD EEPROM and Temp sensor.
