Abstract
The number of times that a non-volatile memory (NVM) can be programmed and erased is substantially increased by utilizing a localized heating element that anneals the oxide that is damaged by tunneling charge carriers when the NVM is programmed and erased. The program and erase voltages are also reduced when heat from the heating element is applied prior to programming and erasing.
