IS61NLF51218A-7.5B3I-TR

The 9 Meg 'NLF/NVF' 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 36 bits and 512K words by 18 bits, fabricated with ISSI's advanced CMOS technology. Incorporating a 'no wait' state feature, wait cycles are eliminated when the bus switches from read to write, or write to read. This device integrates a 2-bit burst counter, high-speed SRAM core, and high-drive capability outputs into a single monolithic circuit.
