Method for achieving very high bandwidth between the levels of a cache hierarchy in 3-Dimensional structures, and a 3-dimensional structure resulting therefrom

摘要

A method of electronic computing, and more specifically, a method of design of cache hierarchies in 3-dimensional chips, and a cache hierarchy resulting therefrom, including a physical arrangement of bits in cache hierarchies implemented in 3 dimensions such that the planar wiring required in the busses connecting the levels of the hierarchy is minimized. In this way, the data paths between the levels are primarily the vias themselves, which leads to very short, hence fast and low power busses.
