DESCRIPTION
The
ICSI
4400 Series is a 4,194,304 x 4-bit high-performance
CMOS Dynamic Random Access Memory. These devices
offer an accelerated cycle access called EDO Page Mode.
EDO Page Mode allows 2,048 or 4096 random accesses within
a single row with access cycle time as short as 20 ns per 4-bit
word.
These features make the 4400 Series ideally suited for high-
bandwidth graphics, digital signal processing, high-performance
computing systems, and peripheral applications.
The 4400 Series is packaged in a 24-pin 300mil SOJ and a 24
pin TSOP-2
