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.

Abstract: Methods, systems, and devices for preventing disturb of untargeted memory cells during repeated access operations of target memory cells are described for a non-volatile memory array. Multiple memory cells may be in electronic communication with a common conductive line, and each memory cell may have an electrically non-linear selection component. Following an access operation (e.g., a read or write operation) of a target memory cell, untargeted memory cells may be discharged by applying a discharge voltage to the common conductive line. The discharge voltage may, for example, have a polarity opposite to the access voltage. In other examples, a delay may be instituted between access attempts in order to discharge the untargeted memory cells.

Abstract: Ferroelectric-modulated Schottky non-volatile memory is disclosed. A resistive memory element is provided that is based on a semiconductive material. Metal elements are formed on a semiconductive material at two places such that two semiconductor-metal junctions are formed. The semiconductive material with the two semiconductor-metal junctions establishes a composite resistive element having a resistance and functions as a relatively fast switch with a relatively low forward voltage drop. Each metal element may couple a terminal to the resistive element. To provide a resistive element capable of being a resistive memory element to store distinctive memory states, a ferroelectric material is provided and disposed adjacent to the semiconductive material to create an electric field from a ferroelectric dipole. The orientation of the ferroelectric dipole changes the resistance of the resistive element to allow it to function as a resistive memory element.
