Cache in your chips!

After digging through the plethora of SPAM (tasty) I get from SystemLogic, I finally found something that I found interesting. Dave has decided to school us on cache.
The fastest cache is closest to the CPU (in modern processors, on the die), and each subsequent layer gets slower, farther from the processor, and (generally) larger. One of the reasons why each progressively-lower level on the memory hiarchy must be larger (we'll look at some exceptions later) is due to the fact that each layer keeps a copy of the information that is in the smaller/faster layer above it.
It's slightly technical, but I love reading about architecture. You may want to check it out here.
