摘要
A three-dimensional Monte Carlo model for analysis of the reliability of Flash memory arrays is developed, and applied to thin tunnel oxide (t(ox) = 5 nm) samples. Good agreement between experimental data and simulation results are obtained, assuming a correlated defect generation in the tunnel oxide of our samples as evidenced in [1]. The impact of correlated defect generation on dielectric breakdown is also addressed by means of a percolation model. It is shown that correlated generation provides no significant degradation of the breakdown lifetime with respect to Poisson statistics.
