IS61WV102416ALL IS61WV102416BLL IS64WV102416BLL 1M x 16 HIGH-SPEED ASYNCHRONOUS JUNE 2014 CMOS STATIC RAM WITH 3.3V SUPPLY FEATURES DESCRIPTION The ISSI IS61WV102416ALL/BLL and IS64WV102416BLL High-speed access times: are high-speed, 16M-bit static RAMs organized as 1024K 8, 10, 20 ns words by 16 bits. It is fabricated using ISSI s high-perfor- High-perfor mance, low-power CMOS process mance CMOS technology. This highly reliable process Multiple center power and ground pins for greater coupled with innovative circuit design techniques, yields noise immunity high-performance and low power consumption devices. Easy memor y expansion with CE and OE op- tions When CE is HIGH (deselected), the device assumes a CE power-down standby mode at which the power dissipation can be re- Fully static operation: no clock or refresh duced down with CMOS input levels. required TTL compatible inputs and outputs Easy memor y expansion is provided by using Chip Enable Single power supply and Output Enable inputs, CE and OE. The active LOW Vdd 1.65V to 2.2V (IS61WV102416ALL) Wr ite Enable (WE) controls both writing and reading of the speed = 20ns for Vdd 1.65V to 2.2V memory.
