Responsive to a memory access resulting in a cache miss in a given processor, the processor determines whether a memory region being accessed is marked as directory-based. Responsive to the given processor determining the memory region is marked as directory-based, the given processor accesses a directory entry corresponding to the memory region to identify a home chip for the page using a directory-based protocol. The given processor forwards the memory access request to the home chip to perform the memory access."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Add-on memory coherence directory","description":"A mechanism is provided for memory coherence in a multiple processor system.
