FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION The ISSI IS61WV51216EDALL and
IS61/64WV51216EDBLL are high-speed, 8M-bit static RAMs organized as 512K words by 16 bits. It is fabri-
cated using ISSI's high-performance
CMOS technology.
This highly reliable process coupled with innovative circuit design techniques, yields high-performance and low power consumption devices.
When CE 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, CE and OE. The active LOW Write Enable (WE) controls both writing and reading of the memory. A data byte allows Upper Byte (UB) and Lower Byte (LB) access.
The device is packaged in the JEDEC standard ...
