At this point, DDR2 memories are available with clock speeds of 200MHz. (DDR2-400), 266MHz. (DDR2-533), and 333MHz. (DDR2-667). At such high speeds, one cannot take the risk of using a conventional ...

As data rates have progressively increased from DDR2 400, DDR2 533, DDR2 667, and now DDR2 800, the complexities associated with the timing and signal integrity of the memory interface has become ...
