Abstract

A nonvolatile memory cell which is highly scalable includes a cell formed in a triple wall. The control gate is negatively biased. By biasing the P-well and drain (or source) positively within a particular voltage range when erasing, GIDL current and degradation from a hole trapping can be diminished and hence scalable technology may be achieved.
