IS43R16800CC  
8Mx16  
128Mb DDR Synchronous DRAM  
JUNE 2009  
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:  
IS43R16800CC is a 4-bank x 2,097,152-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
