K. Imamiya et al., STATISTICAL MEMORY YIELD ANALYSIS AND REDUNDANCY DESIGN CONSIDERING FABRICATION LINE IMPROVEMENT, IEICE transactions on electronics, E76C(11), 1993, pp. 1626-1631
The method to optimize redundancy scheme for memory devices is propose
d. Yield for new generation memories is predicted by failure mode anal
ysis of previous generation memories. Fabrication line improvement and
chip area penalty by the redundancy are taken into account for this y
ield prediction. The actual data of 16 Mbit EPROM failure analysis ind
icate the effectiveness of the prediction.
