Abstract: Structures for a ferroelectric field-effect transistor and methods of forming a structure for a ferroelectric field-effect transistor. The structure comprises a gate stack having a ferroelectric layer, a first conductor layer, and a second conductor layer positioned in a vertical direction between the first conductor layer and the ferroelectric layer. The first conductor layer comprises a first material, the second conductor layer comprises a second material different from the first material, and the second conductor layer is in direct contact with the ferroelectric layer.

Abstract: The structure includes transistors in rows and columns and each having an electric field-based programmable threshold voltage at either a first threshold voltage (VT) or a second VT. The structure further includes first and second signal lines for the rows and columns, respectively. Each first signal line is connected to transistors in a row and each second signal line is connected to transistors in a column. When operated in a switch mode, the transistors may or may not become conductive depending upon their respective VTs. Conductive transistors form connected pairs of first and second signal lines and, thus, create signal paths. The structure can also include mode control circuitry to selectively operate the transistors in either a program mode to set a first VT or an erase mode to set a second VT and to concurrently operate the transistors in the switch mode.
