What the article says around this equation
If is the binding term, the physical question becomes how to raise it. Bandwidth is the product of interface width and data rate per pin, and both are limited by what can be routed off a package. A conventional memory interface runs comparatively few wires a comparatively long distance across a printed circuit board, and both the width and the achievable rate are capped by that distance.
