The flash memory is an NOR type stack flash. The disclosed method performs an over-erased column verification test on a sector of the NOR type stack flash column by column. An over-erased column repair process is individually performed on the columns which do not pass the over-erased column verification test. For the columns processed by the over-erased column repair process but still incapable of passing the over-erased column verification test, an over-erased bit verification test is performed on each bit thereof. The bits incapable of passing the over-erased bit verification test are further processed by an over-erased repair process individually."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Over-erase verification and repair methods for flash memory","description":"Over-erase verification and repair methods for a flash memory.
