Abstract

An integrated circuit is described. The integrated circuit may comprise a multitude of floating-gate electrodes, wherein at least one of the floating-gate electrodes has a lower width and an upper width, the lower width being larger than the upper width, and wherein the at least one of the floating-gate electrodes comprises a transition metal. A corresponding manufacturing method for an integrated circuit is also described.
