Abstract
A thin-film storage transistor includes (a) first and second polysilicon layers of a first conductivity serving, respectively, as a source terminal and a drain terminal of the thin-film storage transistor; (b) a third polysilicon layer of a second conductivity adjacent the first and second polysilicon layers, serving as a channel region of the thin-film storage transistor; (c) a conductor serving as a gate terminal of the thin-film storage transistor; and (d) a charge-trapping region between the conductor and third polysilicon layer, wherein a fourth body layer polysilicon of the second conductivity is included to provide an alternative source of free charge careers to accelerate device operation.
