摘要: Some embodiments include an integrated assembly having a first semiconductor material between two regions of a second semiconductor material. The second semiconductor material is a different composition than the first semiconductor material. Hydrogen is diffused within the first and second semiconductor materials. The conductivity of the second semiconductor material increases in response to the hydrogen diffused therein to thereby create a structure having the second semiconductor material as source/drain regions, and having the first semiconductor material as a channel region between the source/drain regions. A transistor gate is adjacent the channel region and is configured to induce an electric field within the channel region. Some embodiments include methods of forming integrated assemblies.

摘要: Methods, systems, and devices for dirty write on power off are described. In an example, the described techniques may include writing memory cells of a device according to one or more parameters (e.g., reset current amplitude), where each memory cell is associated with a storage element storing a value based on a material property associated with the storage element. Additionally, the described techniques may include identifying, after writing the memory cells, an indication of power down for the device and refreshing, before the power down of the device, a portion of the memory cells based on identifying the indication of the power down for the device. In some cases, refreshing includes modifying at least one of the one or more parameters for a write operation for the portion of the memory cells.

摘要: Methods, systems, and devices for memory cell selection to enable a memory device to select a targeted memory cell during a write operation are described. The memory device may apply a first pulse to a selected bit line of the targeted memory cell while applying a voltage to deselected word lines to prevent current leakage. If the targeted memory is not selected after the first pulse, the memory device may apply a second pulse to the selected bit line while applying a voltage to the deselected word lines. If the targeted memory cell is not selected following the second pulse, the memory device may apply a third pulse to the selected bit line while applying the voltage to the deselected word lines. The memory device may detect a snapback event after any of the pulses if the targeted memory cell is selected.

摘要: The present disclosure includes apparatuses, methods, and systems for performing refresh operations on memory cells. An embodiment includes a memory having a group of memory cells and one or more additional memory cells whose data state is indicative of whether to refresh the group of memory cells, and circuitry configured to apply a first voltage pulse to the group of memory cells to sense a data state of the memory cells of the group, apply, while the first voltage pulse is applied to the group of memory cells, a second voltage pulse having a greater magnitude than the first voltage pulse to the one or more additional memory cells to sense a data state of the one or more additional memory cells, and determine whether to perform a refresh operation on the group of memory cells based on the sensed data state of the one or more additional memory cells.
