Description

NT256D64SH8B0GM is an unbuffered 200-Pin Double Data Rate (DDR) Synchronous DRAM Small Outline Dual In-Line Memory

Module (SO-DIMM), organized as a two-bank 32Mx64 high-speed memory array. The module uses eight 16Mx16 DDR SDRAMs in 400

mil TSOP II packages. 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 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 133 MHz clock speeds and achieves high-speed data transfer rates of up to

266 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.
