The girls over at FiringSquad have posted a second installment to their Memory article.
In DDR memory, both the rising and falling edge of the pulse is used to transfer information. This gives us an effective doubling of bandwidth available. With single data rate memory, the only way we would have achieved that same level of bandwidth improvement would have been to double the clock frequency of the memory. This means that 100Mhz of DDR memory is as effective as 200Mhz of SDR memory.
This really digs down into some history. Ahhhh 30 pin, how I love thee. Anyways, check it out over here.
