Abstract
The present invention relates to an erasing method for nonvolatile memory, which uses forward bias between the source/drain region and body contact to inject majority carriers into the body, and then accelerates the majority carriers by an electric field between the body and the gate to energize the majority carriers to overcome the oxide barrier and to erase the nonvolatile memory.
