Description

NT256S64V8HC0G is unbuffered 168-pin Synchronous DRAM Dual In-Line Memory Modules (DIMMs) which is organized as 32Mx64 high-speed memory arrays and is configured as two 16M x 64 physical bank. The DIMM uses sixteen 16Mx8 SDRAMs in 400mil TSOP II pack-ages. The DIMM achieves high-speed data transfer rates of up to 133MHz by employing a prefetch / pipeline hybrid architecture that supports the JEDEC 1N rule while allowing very low burst power.
