Description
NT1GT72U89D0BV, NT2GT72U4PD0BV, NT2GT72U8PD0BV and NT4GT72U4ND0BV are Registered 240-Pin Double Data Rate 2
(DDR2) Synchronous DRAM Dual In-Line Memory Module (DIMM), organized as a one rank 128Mx72, 256Mx72 high-speed memory
array and two ranks 512MX72 high-speed memory array. The module uses nine 128Mx8 (NT1GT72U89D0BV), eighteen 128Mx8
(NT2GT72U8PD0BV), eighteen 256Mx4 (NT2GT72U4PD0BV) and thirty-six 256Mx4 (NT4GT72U4ND0BV) DDR2 SDRAMs in BGA
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 DDR2 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 up to 333 MHz (or 400 MHz) clock speeds and achieves high-speed data transfer
rates of up to 667Mbps (or 800Mbps ). 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, BA1, and BA2 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.
