<p>Methods and apparatuses for electronic devices such as non-volatile memory devices are described. The memory devices include a multi-layer control dielectric, such as a double or triple layer. The multi-layer control dielectric includes a combination of high-k dielectric materials such as aluminum oxide, hafnium oxide, and/or hybrid films of hafnium aluminum oxide. The multi-layer control dielectric provides enhanced characteristics, including increased charge retention, enhanced memory program/erase window, improved reliability and stability, with feasibility for single or multi state (e.g., two, three or four bit) operation.</p> |
