US Patent 7233501 Interleaved memory heat sink

A heat sink comprises a heat sink base and a row of heat sink extensions that are attached to one side of the heat sink base. An interleaved heat sink structure includes a first row and a second row of heat sink extensions. The first row and the second row of heat sink extensions are coupled respectively to a first and a second heat sink bases. The first and the second heat sink bases are thermally coupled to a first plurality of memory packages and a second plurality of memory packages, respectively. The first row of heat sink extensions is parallel to and at least partially interleaved with the second row of heat sink extensions. A memory heat dissipation control system and a method for assembly a memory part that includes a DIME and two heat sinks are also described.
