DESCRIPTION
The
ISSI
IS41C16257 and the IS41LV16257 are 262,144
x 16-bit high-performance CMOS Dynamic Random Access
Memories. Fast Page Mode allows 512 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 these devices ideal for use in 16- and 32-bit
wide data bus systems.
These features make the IS41C16257 and the IS41LV16257
ideally suited for high band-width graphics, digital signal
processing, high-performance computing systems, and
peripheral applications.
The IS41C16257 and the IS41LV16257 are packaged in a
40-pin, 400-mil SOJ and TSOP (Type II).
