Abstract
A non-volatile memory device includes a substrate and a charge storage layer. The charge storage layer comprises a bottom layer of oxide, a layer of discrete charge storage elements on the bottom layer of oxide, and a top layer of oxide on the charge storage elements. A control gate is on the top layer of oxide. A surface of the top layer of oxide facing a surface of the control gate is substantially planar.
