Claim Text:
1. A field effect transistor device capable of being repeatedly programmed to at least two different static threshold voltage states, comprising: a pair of source/drain regions, a channel region between the pair of source/drain regions, and a gate construction operably proximate the channel region; and the gate construction comprising a conductive gate electrode and comprising a semiconductive material comprising mobile dopants within a dielectric and comprising a mobile dopant barrier dielectric material received between the conductive gate electrode and the channel region, the mobile dopant barrier dielectric material being closer to the channel region than to the conductive gate electrode, the semiconductive material that comprises mobile dopants within a dielectric being closer to the conductive gate electrode than to the channel region, the mobile dopant barrier dielectric material comprising at least one of ZrO
