Intel’s Omni-Directional Interconnect Allows Communication among Chiplets

Intel’s new Omni-Directional Interconnect provides even greater flexibility for communication among chiplets in a package. The top chip can communicate horizontally with other chiplets, similar to EMIB. It can also communicate vertically with through-silicon vias (TSVs) in the base die below, similar to Foveros. And ODI leverages large vertical vias to allow power delivery to the top die directly from the package substrate. Much larger than traditional TSVs, the large vias have lower resistance, providing more robust power delivery simultaneously with higher bandwidth and lower latency enabled through stacking. At the same time, this approach reduces the number of TSVs required in the base die, freeing up more area for active transistors and optimizing die size. (Credit: Intel Corporation)
