Description
NT1GC64B88A0NF and NT2GC64B8HA0NF are 240-Pin Double Data Rate 3 (DDR3) Synchronous DRAM Unbuffered Dual In-Line
Memory Module (UDIMM), organized as one rank of 128Mx64 (1GB) and two ranks of 256Mx64 (2GB) high-speed memory array. Modules
use eight 128Mx8 (1GB) 78-ball BGA packaged devices and sixteen 128Mx8 (2GB) 78-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 DDR3 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 of 533MHz/667MHz clock speeds and achieves high-speed data transfer rates of
1066Mbps/1333Mbps. 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~BA2 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 SPD data
are programmed and locked during module assembly. The remaining 128 bytes are available for use by the customer.
