Description
NT256T64UH4A1FN and NT512T64UH8A1FN 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 and two ranks of 64x64 high-speed memory array. Modules use
four 32Mx16 (NT256T64UH4A1FN) or eight 32Mx16 (NT512T64UH8A1FN) 84-ball FBGA 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 2.66”
long space-saving footprint.
The DIMM is intended for use in applications operating up to 266 MHz (333MHz) clock speeds and achieves high-speed data transfer rates
of up to 533 MHz (667MHz). Prior to any access operation, the device
latency and burst type/ length/operation type must be
programmed into the DIMM by address inputs A0-A12 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.

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,
operation 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-A12 defines the row address (RA0-RA12)
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
