As data is written to the shared memory resource, each processing domain generates a diagnostic code as a function of the data, the memory address for the data, and of a unique identifier corresponding to the processing domain. The diagnostic code is stored with the data for verification when the data is read back. As the data is read back, the processing domain separates the diagnostic code from the data being read and generates another diagnostic code in the same manner as the original diagnostic code. The other diagnostic code is compared to the initial diagnostic code. If both diagnostic codes are the same, the processing domain can be confident that the data read from the shared memory resource is the same as the data that was originally written."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for memory error detection","description":"A system with multiple processing domains sharing a memory resource accessed via a shared memory controller detects a memory error.
