Short for 
Double Data Rate-Synchronous DRAM, a type of 
SDRAM that supports data transfers on both edges of each clock cycle (the rising and falling edges), effectively doubling the memory chip's data throughput. DDR-SDRAM also consumes less power, which makes it well-suited to 
notebook computers. DDR-SDRAM is also called 
SDRAM II. and 
DDRAM.
U biti, to ti je maltene ista memorija. Ubaci, ne može ništa otić, ako radi radiće, ako ne, neće ti je komp prepoznati.
