A power-on self-test (POST) is executed, and an initial backup memory is reserved in a memory. An operating system (OS) is executed, and data is loaded from a kernel region of the OS in the memory into a mirror region, so that when a processor accesses the data in the kernel region, it also accesses the data in the mirror region. An uncorrectable error (UE) is detected to determine a damaged page, and a backup page is selected from the initial backup memory or dynamically obtained from the OS to back up data in the damaged page. A mapping address of the damaged page and backup page are recorded into a page mapping table in a memory controller. Accordingly, when the OS accesses the damaged page, the memory controller accesses the backup page instead according to the page mapping table."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Data protection method for damaged memory cells","description":"A data protection method for damaged memory cells is provided.
