32Mx8, 16Mx16

256Mb DDR Synchronous DRAM

AUGUST 2010

FEATURES:

•ꢀ Vd d =Vd d q = 2.5V+0.2V (-5, -6, -75)

•ꢀ Double data rate architecture; two data transfers

per clock cycle.

•ꢀ Bidirectional , data strobe (DQS) is transmitted/

received with data

•ꢀ Differential clock input (CLK and /CLK)

DESCRIPTION:

IS43/46R83200B is a 4-bank x 8,388,608-word x8bit,

IS43/46R16160B is a 4-bank x 4,194,304-word x 16bit

double data rate synchronous DRAM , with SSTL_2

interface. All control and address signals are referenced

to the rising edge of CLK. Input data is registered on

both edges of data strobe, and output data and data

strobe are referenced on both edges of CLK. The device

achieves very high speed clock rate up to 200 MHz.

•ꢀ DLL aligns DQ and DQS transitions with CLK

transitions edges of DQS

•ꢀ Commands entered on each positive CLK edge;

•ꢀ Data and data mask referenced to both edges of
