DDR stands for Double Data Rate. So you take the frequency it says and multiply it by 2. EDIT: A more detailed explanation is that most electronics operate on a clock that oscillates between 0 and 1. Now most electronics only update on rising action 0->1 or falling action 1->0. DDR operates on both rising and falling action of the clock, therefore it refreshes at 800MHz with a 400MHz clock.
