Data from 4-Mb and 16-Mb memory chips show that a new method is required to predict the yield of very large memory chips with redundant word and bit lines. A model developed to do this indicates that gigabit memory chips, with a yield of less than 90%, may be less productive than 256-Mb "cut-down" chips.<
