KEY TIMING PARAMETERS
DESCRIPTION
The
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
