Abstract:
A multi-path transistor includes an active region including a channel region and an impurity region. A gate is dielectrically separated from the channel region. A signal line is dielectrically separated from the impurity region. A conductive shield is disposed between, and dielectrically separated from, the signal line and the channel region. In some multi-path transistors, the channel region includes an extension-channel region under the conductive shield and the multi-path transistor includes different conduction paths, at least one of the different conduction paths being in the extension-channel region to conduct substantially independent of a voltage on the signal line. In other multi-path transistors, the conductive shield is operably coupled to the impurity region and the multi-path transistor includes different conduction paths, at least one of the different conduction paths being under the conductive shield to conduct substantially independent of a voltage on the signal line.

Various embodiments comprise apparatuses and methods including a memory array having alternating levels of semiconductor materials and dielectric material with strings of memory cells formed on the alternating levels. One such apparatus includes a memory array formed substantially within a cavity of a substrate. Peripheral circuitry can be formed adjacent to a surface of the substrate and adjacent to the memory array. Additional apparatuses and methods are described.
Abstract:
Methods of operating a memory include performing a memory access operation, obtaining an address corresponding to a subsequent memory access operation prior to stopping the memory access operation, stopping the memory access operation, sharing charge between access lines used for the memory access operation and access lines to be used for the subsequent memory access operation, and performing the subsequent memory access operation.
Abstract:
Various apparatuses, including three-dimensional (3D) memory devices and systems including the same, are described herein. In one embodiment, a 3D memory device can include at least two sources; at least two memory arrays respectively formed over and coupled to the at least two sources; and a source conductor electrically respectively coupled to the at least two sources using source contacts adjacent one or more edges of the source.
