Abstract

We performed a comprehensive analysis of the voltage-to-erase (Verase) distribution in SST ESF3 split-gate flash memory cell arrays. It was shown that Verase distribution is mostly determined by the tunneling voltage variations. Other factors, such as distributions of coupling ratios and FG channel parameters, have only a minor effect on Verase variability.
