are high-speed, 16M-bit static RAMs organized as 1024K
words by 16 bits. It is fabricated using
ISSI
's high-perfor-
mance 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 re-
duced 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 48-pin
TSOP Type I and 48-pin Mini BGA (9mm x 11mm).
