描述 Description

NT256S72V89A0G is unbuffered 168-pin Synchronous DRAM Dual In-Line Memory Modules (DIMM) which is organized as 32Mx72 high-speed memory arrays and is configured as one 32M x 72 physical bank. The DIMM uses nine 32Mx8 SDRAMs in 400mil TSOP II packages. 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.
