A directory structure at a shared point in the interconnect that records which caches may hold a line, so coherency requests are sent only to those caches instead of broadcast to all.

- Design & Architecture, Memory and cache
Notes
Essential above a handful of cores, since broadcast snooping bandwidth grows with the square of the agent count.
