high-speed, 8M bit static RAMs organized as 1M words
by 8 bits. It is fabricated 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
CS1
is HIGH (deselected) or when CS2 is LOW
(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.
The IS62WV10248DALL and IS62WV10248DBLL are
packaged in the JEDEC standard 48-pin mini BGA (9mm
x 11mm) and 44-Pin TSOP (TYPE II).
