DATA SHEET  
128M bits Self Terminated Interface  
DDR SDRAM  
DC0122A (4M words × 32 bits)  
Description  
Pin Configurations  
The DC0122A is a 128M bits self terminated interface  
DDR SDRAM organized as 1,048,576 words × 32 bits  
× 4 banks. Read and write operations are performed at  
the cross points of the CK and the /CK. This high-  
speed data transfer is realized by the 4 bits prefetch  
pipelined-architecture. Data strobe (DQS) both for read  
and write are available for high speed and reliable data  
bus design.  
/xxx indicates active low signal.
