  • Patent number: 10923387
    Abstract: An array of gated devices includes a plurality of gated devices arranged in rows and columns and individually including an elevationally inner region, a mid region elevationally outward of the inner region, and an elevationally outer region elevationally outward of the mid region. A plurality of access lines are individually laterally proximate the mid regions along individual of the rows. A plurality of data/sense lines are individually elevationally outward of the access lines and electrically coupled to the outer regions along individual of the columns. A plurality of metal lines individually extends along and between immediately adjacent of the rows elevationally inward of the access lines. The individual metal lines are directly against and electrically coupled to sidewalls of the inner regions of each of immediately adjacent of the rows. The metal lines are electrically isolated from the data/sense lines. Other arrays of gated devices and methods of forming arrays of gated devices are disclosed.

  • Patent number: 10923205
    Abstract: A method of forming a memory device having magnetic tracks individually comprising a plurality of magnetic domains having domain walls, includes forming an elevationally outer substrate material of uniform chemical composition. The uniform composition material is partially etched into to form alternating regions of elevational depressions and elevational protrusions in the uniform composition material. A plurality of magnetic tracks is formed over and which angle relative to the alternating regions. Interfaces of immediately adjacent of the regions individually form a domain wall pinning site in individual of the magnetic tracks. Other methods, including memory devices independent of method, are disclosed.

  • Publication number: 20210036162
    Abstract: Some embodiments include an integrated assembly having a pillar of semiconductor material. The pillar has a base region, and bifurcates into two segments which extend upwardly from the base region. The two segments are horizontally spaced from one another by an intervening region. A conductive gate is within the intervening region. A first source/drain region is within the base region, a second source/drain region is within the segments, and a channel region is within the segments. The channel region is adjacent to the conductive gate and is vertically disposed between the first and second source/drain regions. Some embodiments include methods of forming integrated assemblies.

  • Patent number: 10410737
    Abstract: Methods, systems, and devices for recovering fatigued ferroelectric memory cells are described. Recovery voltages may be applied to a ferroelectric memory cell that is fatigued due to repeated access (read or write) operations. The recovery voltage may have a greater amplitude than the access voltage and may include multiple voltage pulses or a constant voltage. The recovery operation may be performed in the background as the memory array operates, or it may be performed when a host device is not actively using the memory array. The recovery operations may be performed periodically or may include discrete series of pulses distributed among several instances.
