Description
NT256T64UH4B0FN, NT512T64UH8B0FN, NT1GT64U8HB0BN, NT256T64UH4B0CN, NT512T64UH8B0CN, and NT1GT64U8HB0AN
are unbuffered 200-Pin Double Data Rate 2 (DDR2) Synchronous DRAM Small Outline Dual In-Line Memory Module (SO-DIMM),
organized as one rank of 32x64 (256MB), two ranks of 64x64 (512MB), and two ranks of 128x64(1GB) high-speed memory array. Modules
use four 32Mx16 (256MB) and eight 32Mx16 (512MB) 84-ball BGA packaged devices. Modules use sixteen 64Mx8 (1GB) 60-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 DDR2 SDRAM DIMMs provide a high-performance,
flexible 8-byte interface in a space-saving footprint.
The DIMM is intended for use in applications operating of 266MHz/333MHz/400MHz clock speeds and achieves high-speed data transfer
rates of 533MHz/667MHz/800MHz. 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 and BA1 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 serial PD
data are programmed and locked during module assembly. The remaining 128 bytes are available for use by the customer.

Function
The positive line of the differential pair of system clock inputs which drives the input to the
Positive
on-DIMM PLL. All the DDR2 SDRAM address and control inputs are sampled on the rising
Edge
edge of their associated clocks.
Negative The negative line of the differential pair of system clock inputs which drives the input to the
Edge on-DIMM PLL.

Activates the 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 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.
When sampled at the positive rising edge of the clock,
to be executed by the SDRAM.
Reference voltage for SSTL-18 inputs
On-Die Termination control signals
Selects which SDRAM bank is to be active.
During a Bank Activate command cycle, A0-A13 defines the row address (RA0-RA13)
when sampled at the rising clock edge.
During a Read or Write command cycle, A0-A9, A11 defines the column address
(CA0-CA10) when sampled at the rising clock edge. 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 define 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 to control
which bank(s) to precharge. If AP is high all 4 banks will be precharged regardless of the
state of BA0/BA1. If AP is low, then BA0/BA1 are used to define which bank to pre-charge.

Supply
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. DM8 is associated with check bits
CB0-CB7, and is not used on x64 modules.
Address inputs. Connected to either V
DD
or V
SS
on the system board to configure the
Serial Presence Detect EEPROM address.
This bi-directional pin is used to transfer data into or out of the SPD EEPROM. A resistor
must be connected from the SDA bus line to V

to act as a pull-up.
This signal is used to clock data into and out of the SPD EEPROM. A resistor may be
