Are you talking about the memory chips that you buy and put in the memory slots? If so explain how amd has memory inside the cpu etc?
Im guessing you are talking about a different type of memory... thanks for any help on the subject.
ps I found this site to be pretty helpful

The controller and the memory are seperate components. You buy the memory but not the controller, well, you buy it, but not seperately, it's on your motherboard or CPU. The controller assists the CPU with memory accesses by setting the appropriate control signals so that the memory itself returns the data being read or writes the data being provided. AMD controllers, being on the same chip thus physically closer and running on the same clock, can handle requests sooner after the CPU makes them. So the upside is that your memory accesses can be faster. The downsides are, one, your chip is more complex, and two, it's not quite as easy to make changes to the architecture such as switch to DDR2 memory because both the CPU AND the motherboard need to have nontrivial changes.
