You don't know what you are talking about. Memory controllers are typically onchip.

"You don't know what you are talking about" is not a great response to someone who's writing more substantive posts than you.

If by on chip you mean on CPU I agree: https://en.wikipedia.org/wiki/Memory_controller
But, that's part of the CPU packaging, a signal needs to get to these pins on the bottom of the CPU and that takes time.
Here is a picture, from the center of the CPU, to the bottom edge of the furthest part of the DIM then up. http://harddiskdirect.com/media/catalog/product/cache/1/imag...
PS: A DIMM is just over 5 inches wide and 0.7 inches tall so if was centered physically on top of a CPU that's 3 inches right there.
