    摘要: Methods and devices are disclosed, such as those involving forming a charge trap for, e.g., a memory device, which can include flash memory cells. A substrate is exposed to temporally-separated pulses of a titanium source material, a strontium source material, and an oxygen source material capable of forming an oxide with the titanium source material and the strontium source material to form the charge trapping layer on the substrate.

    摘要: A method of reducing an energy consumption of a wireless network, the method including periodically entering a sleep mode by a receiver node, broadcasting a signal simultaneously across a wide band frequency range, upon waking up from the sleep mode, listening by the receiver node to only a first narrow part of the wide band frequency range, the receiver node subsequently either returning to sleep if a signal strength of the broadcasted signal is less than a predefined signal strength threshold, or staying awake for an additional period of time if the signal strength of the broadcasted signal is greater than the predefined signal strength threshold.

    摘要: Some embodiments include memory cells which contain, in order; a first electrode material, a first metal oxide material, a second metal oxide material, and a second electrode material. The first metal oxide material has at least two regions which differ in oxygen concentration relative to one another. One of the regions is a first region and another is a second region. The first region is closer to the first electrode material than the second region, and has a greater oxygen concentration than the second region. The second metal oxide material includes a different metal than the first metal oxide material. Some embodiments include methods of forming memory cells in which oxygen is substantially irreversibly transferred from a region of a metal oxide material to an oxygen-sink material. The oxygen transfer creates a difference in oxygen concentration within one region of the metal oxide material relative to another.
