1Mx16 HIGH-SPEED ASYNCHRONOUS
CMOS STATIC RAM WITH 3.3V/1.8V SUPPLY
FEATURES
DESCRIPTION
The ISSI IS61/64WV102416DALL/BLL are high-speed, 16M
bit static RAMs organized as 1024K words by 16 bits. It is
fabricated using ISSI's high-performance CMOS technology.
High-speed access time: 10ns, 12ns
High- performance, low power CMOS process
Multiple center power and ground pins for
greater noise immunity
This highly reliable process coupled with innovative circuit
design techniques, yields high-performance and low power
consumption devices.
Easy memory expansion with CS# and OE#
TTL compatible inputs and outputs
Single power supply
When CS# is HIGH (deselected), the device assumes a
standby mode at which the power dissipation can be reduced
down with CMOS input levels. Easy memory expansion is
provided by using Chip Enable and Output Enable inputs.
The active LOW Write Enable (WE#) controls both writing
and reading of the memory.
