DESCRIPTION
The ISSI IS41LV8205A is 2,097,152 x 8-bit high-perfor-
mance CMOS Dynamic Random Access Memory. The
Fast Page Mode allows 2,048 random accesses within a
single row with access cycle time as short as 20 ns per 4-
bit word.
These features make the IS41LV8205A ideally suited for
high-bandwidth graphics, digital signal processing, high-
performance computing systems, and peripheral
applications.
The IS41LV8205A is packaged in 28-pin 300-mil SOJ with
JEDEC standard pinouts.
