EDD2516AKTA-5CLI (16M words × 16 bits, DDR400)  
Description  
Pin Configurations  
The EDD2516AKTA-5 is a 256M bits DDR SDRAM  
organized as 4,194,304 words × 16 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 2 bits prefetch-pipelined  
architecture. Data strobe (DQS) both for read and  
write are available for high speed and reliable data bus  
design. By setting extended mode register, the on-chip  
Delay Locked Loop (DLL) can be set enable or disable.  
/xxx indicates active low signal.
