Description
NT128D64SH4BBGM is an unbuffered 200-Pin Double Data Rate (DDR) Synchronous DRAM Small Outline Dual In-Line Memory
Module (SO-DIMM), organized as a one-bank 16Mx64 high-speed memory array. The module uses four 16Mx16 DDR SDRAMs in 400
mil TSOP II packages. These DIMMs are manufactured using raw cards developed for broad industry use as reference designs.
use of these common design files minimizes electrical variation between suppliers. All NANYA DDR 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 166 MHz clock speeds and achieves high-speed data transfer rates of up to
333 MHz. Prior to any access operation, the device
CAS
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 2,048-bit 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.

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 CK. 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 DDR 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

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 defines the column address (CA0-CA9)
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.
