Parity information suitable for single error correct and double error detect (SEC-DED) is also stored in association with the SPD information in the nonvolatile memory. The combination of SPD information and parity information is organized into codewords addressable at each memory location. During an initialization period occurring after a power on reset and before the SPD device is accepting I2C commands, the SPD device checks each memory location (codeword) for errors. Each error detected is counted to provide an indicator of device health. Before the initialization period expires, the SPD device writes a corrected codeword back to the nonvolatile memory."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Serial presence detect reliability","description":"A serial presence detect (SPD) device includes nonvolatile memory to store SPD information.
