Abstract
Technology for determining a test flow for testing memory during a production phase. The following are accessed: a list of test items with a number of candidate test item conditions for each test item, defects (e.g., bad blocks) detected by each test item condition, a list of benchmark defects (e.g., bad blocks), and judgement criteria. The defects (e.g., bad blocks) for the candidate test item conditions may be compared with the benchmark defects (e.g., bad blocks) in view of judgement criteria. Based on the comparison, at least one test item may be eliminated resulting in a set of remaining test items. A production phase test flow having a test item condition for each remaining test item may be generated.
