The
ISSI
IS41C16128 is a 131,072 x 16-bit high-performance
CMOS Dynamic Random Access Memory. The IS41C16128
offers an accelerated cycle access called EDO Page Mode.
EDO Page Mode allows 256 random accesses within a
single row with access cycle time as short as 12 ns per 16-
bit word. The Byte Write control, of upper and lower byte,
makes the IS41C16128 ideal for use in 16-, 32-bit wide data
bus systems.
These features make the IS41C16128 ideally suited for
high band-width graphics, digital signal processing,
high-performance computing systems, and peripheral
applications.
The IS41C16128 is packaged in a 40-pin 400-mil SOJ and
TSOP (Type II).
