An integrated circuit and method of forming an integrated circuit having a
memory portion minimizes an amount of oxidation of nanocluster storage
elements in the memory portion. A first region of the integrated circuit
has non-memory devices, each having a control electrode or gate formed of
a single conductive layer of material. A second region of the integrated
circuit has a plurality of memory cells, each having a control electrode
of at least two conductive layers of material that are positioned one
overlying another. The at least two conductive layers are at
substantially a same electrical potential when operational and form a
single gate electrode. In one form each memory cell gate has two
polysilicon layers overlying a nanocluster storage layer.
