In some embodiments, the non-volatile memory device can include a resistive two-terminal selector that can be in a low resistive state or a high resistive state depending on the voltage being applied. A MOS (“metal-oxide-semiconductor”) transistor in addition to a capacitor or transistor acting as a capacitor can also be included. A first terminal of the capacitor can be connected to a voltage source, and the second terminal of the capacitor can be connected to the selector device. A floating gate of an NMOS transistor can be connected to the other side of the selector device, and a second NMOS transistor can be connected in series with the first NMOS transistor.

    摘要: A method of forming a non-volatile memory device. The method forms a vertical stack of first polysilicon material and a second polysilicon material layer isolated by a dielectric material. The polysilicon material layers and the dielectric material are subjected to a first pattern and etch process to form a first wordline associated with a first switching device and a second wordline associated with a second switching device from the first polysilicon material layer, and a third wordline associated with a third switching device and a fourth wordline associated with a fourth switching device from the second polysilicon material. A via opening is formed to separate the first wordline from the second wordline and to separate the third wordline from the fourth wordline. An amorphous silicon switching material is deposited conformably overlying the via opening. A metal material fills the via opening and connects to a common bitline.

    摘要: Providing for capacitive programming of two-terminal memory devices is described herein. By way of example, a capacitance circuit can be precharged to a predetermined program voltage to facilitate programming one or more memory cells. The capacitance circuit can be disconnected from a power source and connected instead to the memory cell(s), enabling charge stored by the capacitance circuit to discharge through the memory cell(s). A current at the memory cell(s) can program the cell, while a total amount of discharge is limited to the charge stored by the capacitance circuit. Limiting the total charge can serve to also limit joule heating of the target memory cell, power consumption of a memory device, as well as other benefits.
