NETSOL S7B641835M
The S7B643635M and S7B641835M are 75,497,472-bit Synchronous Static Random Access Memory designed for high performance. It is organized as 2M(4M) words of 36(18) bits and integrates address and control registers, a 2-bit burst address counter and added some new functions for high performance applications; GW, BW, LBO, ZZ. The S7B643635M and S7B641835M are fabricated using high performance CMOS technology and is available in a 100pin TQFP package and 165FBGA package.FEATURES

GENERAL DESCRIPTION
Write cycles are internally self-timed and synchronous. Full bus-width write is done by GW, and each byte write is performed by the combination of WEx and BW when GW is high. And with CS1 high, ADSP is blocked to control signals.
