The data storage system includes a memory device that may include m nonvolatile memories, where m is a natural number, and a memory controller that may program data to at least the first to mth pages. The data storage system also includes a RAID controller that may generate a RAID configuration signal, including a RAID operation signal for determining whether to activate or deactivate a RAID operation of the memory device, and that may transmit the data and the RAID configuration signal to the memory controller. The memory controller may generate a RAID parity using first to (m−1)th data from the RAID controller and program the first to (m−1)th data to the first to (m−1)th pages and the RAID parity to the mth page when the RAID operation signal is activated, but program the first to mth data received from the RAID controller to the first to mth pages when the RAID operation signal is deactivated."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Data storage system, data storage device and RAID controller","description":"Provided are a data storage system, a data storage device and a RAID controller, which can control RAID operation and a RAID operating method of a memory device by transmitting a RAID configuration si","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9812224","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
