Abstract:
Device and design structures for memory cells in a non-volatile random access memory (NVRAM). The device structure includes a semiconductor body in direct contact with the insulating layer, a control gate electrode, and a floating gate electrode in direct contact with the insulating layer. The semiconductor body includes a source, a drain, and a channel between the source and the drain. The floating gate electrode is juxtaposed with the channel of the semiconductor body and is disposed between the control gate electrode and the insulating layer. A first dielectric layer is disposed between the channel of the semiconductor body and the floating gate electrode. A second dielectric layer is disposed between the control gate electrode and the floating gate electrode.
