IS41LV16257B

256K x 16 (4-MBIT) DYNAMIC RAM

WITH FAST PAGE MODE

DESCRIPTION

The

ISSI

IS41LV16257B is 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 IS41LV16257B ideally suited

for high band-width graphics, digital signal processing,

high-performance computing systems, and peripheral

applications.

The IS41LV16257B is packaged in a 40-pin, 400-mil

SOJ and TSOP (Type II).
