Classification: CPC G | IPC G

Claim 15:
16. An electronic device of a single electronic device package, the electronic device including:
multiple integrated circuit memory dies configured as a system shared memory, and at least a portion of the system shared memory of the memory dies mapped to include at least a portion of a memory coherence directory; and
wherein the system shared memory includes a logic base die included in the single electronic device package and separate from the logic base die excluding a system processor, the logic base die including at least one memory controller configured to manage access to the system shared memory by at least one separate device, and logic circuitry configured to determine memory coherence state information for data stored in the system shared memory, grant access to stored memory coherence state information stored in the system shared memory in response to an atomic memory request, wherein the stored memory coherence state information for a memory word is accessed by the logic circuitry remapping an address of the memory word included in the atomic memory request, and include the stored memory coherence state information in a packetized message of a packetized input/output (I/O) protocol that is sent in response to the atomic memory request.
