Hi,
PC3200 is a DDR RAM. DDR stands for Double Data Rate. Essentially it performs operations twice for each clock. The clock is 200 MHz, hence the 400 MHz reference. Hope this helps.

Lead3 has got it. The actual clock of the RAM is 200 MHz, but since it sends and recives data in one clock cycle (as opposed to regular SD RAM, which requires two clock cycles to do this), you are effectivley getting 400 MHz RAM.
