After repair of a memory array is completed, if a target word line in a failure state exists in the memory array, a second numerical value is written into the target word line, and then it is determined, according to a numerical value outputted by each word line in the memory array, whether there are at least two word lines in an on-state in the memory array; if there are at least two word lines in an on-state simultaneously in the memory array, a current value generated by the target word line in an on-to-off process is detected; when the current value generated by the target word line in the on-to-off process is greater than a preset current threshold, it is determined that the target word line has a repair fault."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus of testing word line to detect fault after repair","description":"Embodiments of the present disclosure provide a method and an apparatus of testing a word line.
