    摘要: A semiconductor device comprises a recessed access device that includes a first pillar, a second pillar, a channel region connecting the first and second pillars, and a gate disposed over the channel region. The channel region has a width that is narrower than widths of the first pillar and the second pillar. An array of recessed access devices comprises a plurality of pillars protruding from a substrate, and a plurality of channel regions. Each channel region has a width that is less than about 10 nm and couples neighboring pillars to form a plurality of junctionless recessed access devices. A method of forming at least one recessed access device also comprises forming pillars over a substrate, forming at least a channel region coupled with the pillars, the channel region having a relatively narrow width, and forming a gate at least partially surrounding the channel region on at least three sides.

    摘要: A high density non-volatile memory device is provided that uses one or more volatile elements. 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 deep trench MOS (“metal-oxide-semiconductor”) transistor having a floating gate with small area relative to conventional devices can be provided, in addition to a capacitor or transistor acting as a capacitor. 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. The small area floating gate of the deep trench transistor can be connected to the other side of the selector device, and a second transistor can be connected in series with the deep trench transistor.
