Abstract
A heating element is utilized to improve the bias conditions of an E2PROM cell during program and erase operations. The heating element can also be used to anneal or condition the cell for improved charge storage. During a program or an erase operation, the cell's control gate and read transistor are set to ground. The heating element then has a voltage potential applied across its terminals, causing current to flow in this resistor. As the current density increases, the resistor begins to generate heat. This heat is thermally coupled into the cell's floating gate, causing its temperature to rise.
