A MEMORY REDUNDANCY ALLOCATION SYSTEM AND A METHOD OF REDUNDANCY ALLOCATION

摘要

A means for providing a minimum repair solution in a memory redundancy allocation system by finding an optimal solution assuming the availability of unlimited spare resources and then, under the same conditions, adapting the optimal solution obtained to an existing ratio of spare resources. Use of the adapting means can reduce the required amount of redundancy and number of waste repairs and enhance device reliability, thus improving overall yield and the profitability of a memory manufacturer.
