Abstract
A memory structure including a semiconductor substrate, an insulator layer formed on the semiconductor substrate and a gate layer formed on the insulator layer is disclosed. The insulator layer includes a first nanocrystal implanted region proximate to the gate layer and a second nanocrystal implanted region proximate to the semiconductor substrate, wherein the first nanocrystal implanted region has an average nanocrystal concentration which is higher than an average nanocrystal concentration of the second nanocrystal implanted region.
