Some embodiments include a memory cell with two transistors and one capacitor. The transistors are a first transistor and a second transistor. The capacitor has a first node coupled with a source/drain region of the first transistor, and has a second node coupled with a source/drain region of the second transistor. The memory cell has a first body region adjacent the source/drain region of the first transistor, and has a second body region adjacent the source/drain region of the second transistor. A first body connection line couples the first body region of the memory cell to a first reference voltage. A second body connection line couples the second body region of the memory cell to a second reference voltage. The first and second reference voltages may be the same as one another, or may be different from one another.

Various embodiments of the present application are directed towards a metal-ferroelectric-metal-insulator-semiconductor (MFMIS) memory device, as well as a method for forming the MFMIS memory device. According to some embodiments of the MFMIS memory device, a first source/drain region and a second source/drain region are vertically stacked. An internal gate electrode and a semiconductor channel overlie the first source/drain region and underlie the second source/drain region. The semiconductor channel extends from the first source/drain region to the second source/drain region, and the internal gate electrode is electrically floating. A gate dielectric layer is between and borders the internal gate electrode and the semiconductor channel. A control gate electrode is on an opposite side of the internal gate electrode as the semiconductor channel and is uncovered by the second source/drain region. A ferroelectric layer is between and borders the control gate electrode and the internal gate electrode.
