The ISSI IS65WV25616ALL/IS65WV25616BLL are highspeed, low power, 4M bit SRAMs organized as 256K words by 16 bits. It is fabricated using ISSI's high-performance CMOS technology. This highly reliable process coupled with innovative circuit design techniques, yields highperformance and low power consumption devices. When CS1 is HIGH (deselected) or when CS1 is LOW, and both LB and UB are HIGH, the device assumes a standby mode at which the power dissipation can be reduced down with CMOS input levels.
