    摘要: Methods and apparatuses for nanoenabled memory devices and anisotropic charge carrying arrays are described. In an aspect, a memory device includes a substrate, a source region of the substrate, and a drain region of the substrate. A population of nanoelements is deposited on the substrate above a channel region, the population of nanolements in one embodiment including metal quantum dots. A tunnel dielectric layer is formed on the substrate overlying the channel region, and a metal migration barrier layer is deposited over the dielectric layer. A gate contact is formed over the thin film of nanoelements. The nanoelements allow for reduced lateral charge transfer. The memory device may be a single or multistate memory device. In a multistate memory device which comprises one or more quantum dots or molecules having a plurality of discrete energy levels, a method is disclosed for charging and/or discharging the device which comprises filling each of the plurality of discrete energy levels of each dot or molecule with one or more electrons, and subsequently removing individual electrons at a time from each discrete energy level of the one or more dots or molecules.

    摘要: A nonvolatile memory cell includes a substrate comprising a source, drain, and channel between the source and the drain. A tunnel dielectric layer overlies the channel, and a localized charge storage layer is disposed between the tunnel dielectric layer and a control dielectric layer. A gate electrode has a first surface adjacent to the control dielectric layer, and the first surface includes a midsection and two edge portions. According to one embodiment, the midsection defines a plane, and at least one edge portion extends away from the plane. Preferably, the edge portion extending away from the plane converges toward an opposing second surface of the gate electrode. According to another embodiment, the gate electrode of the nonvolatile memory cell includes a first sublayer and a second sublayer of a different width on the first sublayer.
