Abstract

The single-electron general-purpose device simulator is improved to carry out a wide-range transient analysis from 1 ps to 10 years. We apply this simulator to a floating gate (FG) nonvolatile memory cell in order to simulate a degradation mode of data retention owing to the direct tunneling enhanced by the fixed charge stored by a local trap in an interpoly dielectric. The scaling impact of ideal high-K interpoly dielectric FG nonvolatile memory cell is also investigated.
