Claim 19:
20. A semiconductor device comprising:
a CMOS circuit including a first transistor of a first conductivity type and a second transistor of a second conductivity type;
a third transistor including a gate electrode, a channel, and a gate insulating film, the gate insulating film including a ferroelectric material; and
a contact electrode connected to the gate electrode of the third transistor, a drain of the first transistor, and a drain of the second transistor, wherein
the channel of the third transistor is laterally between a source electrode of the third transistor and a drain electrode of the third transistor such that the channel of the third transistor contacts a sidewall of the source electrode of the third transistor and a sidewall of the drain electrode of the third transistor,
the gate electrode is spaced apart vertically from the channel, does not vertically overlap the source electrode of the third transistor, and does not vertically overlap the drain electrode of the third transistor,
the ferroelectric material includes at least one of HfO, HfxZr1-xO, and ZrO, and
the ferroelectric material is doped with at least one of Si, Al, Zr, Y, La, Gd, Sr, and Hf.
