IS42S16160A
DESCRIPTION
IS42S83200A is a synchronous 256Mb SDRAM and is
organized as 4-bank x 8,388,608-word x 8-bit; and
IS42S16160A is organized as 4-bank x 4,194,304-word x
16-bit. All inputs and outputs are referenced
to the rising
edge of CLK.
IS42S83200A and IS42S16160A achieve very
high speed clock rates up to 166MHz, and are
suitable for main memories or graphic
memories in computer systems.
