IS61NLP25672-250B1集成电路（IC）的存储器规格书PDF中文资料

DESCRIPTION

The 18 Meg NLP/NVP product family feature high-speed, low-power synchronous static RAMs designed to provide a burstable, high-performance, no wait state, device for networking and communications applications. They are organized as 256K words by 72 bits, 512K words by 36 bits and 1M words by 18 bits, fabricated with ISSIs advanced CMOS technology.

FEATURES
