Each of the blocks includes pages each being a unit of reading of the data. The controller, when data of a first page is read in response to the data read request from the external apparatus, reads data of an other page other than the first page in a block from which the data is read, and calculates a number of errors of the data in the other page, and rewrites the data into an other block when the block from which the data is read satisfies a predetermined condition on the error based on the calculated number of errors."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Nonvolatile memory apparatus and control method of nonvolatile memory apparatus","description":"A nonvolatile memory apparatus is provided with a nonvolatile memory including a plurality of blocks each being a recording area of the data and a unit of erasing of the data, and a controller for con","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9804921","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.
