According to one exemplary embodiment, a method for fabricating a flash memory cell in a semiconductor die includes forming a control gate stack overlying a floating gate stack in a memory region of a substrate, where the floating gate stack includes a floating gate overlying a portion of a dielectric one layer. The floating gate includes a portion of a metal one layer and the dielectric one layer includes a first high-k dielectric material. The control gate stack can include a control gate including a portion of a metal two layer, where the metal one layer can include a different metal than the metal two layer. |
