文摘A new approach to repair memory chips with redundancy is proposed.This approach is based on the minimization of the repair cost.Algorithms for cost driven repair are presented.The algorithms can be ex- ecuted either on-line(concurrently with the testing of the memory),or off-line(at completion of testing). Analytical expressions for the repair cost under both circumstances are given.The presented algorithms are also perfect in the sense that they can correctly diagnose a repairable/unrepairable memory and find the optimal repair-solution.
