Someone, about a week ago, asked about JFET use in logic circuits.
It turns out that the questioner was a bit ahead of the times.
There's a relatively new device called a G4-FET that's made up of a
MOSFET and a JFET, has 4 gates and can be used to make a 3-input NOT-
majority logic element.
Read about the construction here:

And its use in logic here:
