DDR SDRAM  
DOUBLE DATA RATE  
(DDR) SDRAM  
Timing – Cycle Time  
7.5ns @ CL = 2.5 (PC2100)  
10ns @ CL = 2.5 (PC1600)  
-75A  
-8A  
Part number example:

dataꢀ i.e.ꢀ source-synchronous data capture (x16 has two –  
one per byte)  
Internalꢀ pipelined double-data-rate (DDR) architecture;  
two data accesses per clock cycle  
Differential clock inputs (CK and CK#)  
Commands entered on each positive CK edge  
DꢁS edge-aligned with data for READs; center-aligned  
with data for WRITEs  
DLL to align Dꢁ and DꢁS transitions with CK
