Bringing the memory close to the processor is obviously a good idea forreducing latency, but the memory is not a monolith: It includes submodules, and their arrangement determines the effectiveness of using 3D technology. The authors look at various scenarios for arranging the CPU relative to the memory modules and provide a quantitative comparison.
