AS4C64M16D2A-25BIN Memory Size, Alliance Memory AS4C64M16D2A-25BIN, SDRAM 1Gbit Surface Mount, 400MHz, 84-Pin FBGA

The Alliance Memory AS4C64M16D2A is a high-speed CMOS Double-Data-Rate-Two (DDR2), synchronous dynamic random- access memory (SDRAM) containing 1024 Mbits in a 16-bit wide data I/Os. It is internally configured as a 8-bank DRAM, 8 banks x 8Mb addresses x 16 I/Os. The device is designed to comply with DDR2 DRAM key features such as posted CAS# with additive latency, Write latency = Read latency -1, Off-Chip Driver (OCD) impedance adjustment, and On Die Termination(ODT).
