  • Patent number: 10998221
    Abstract: Some embodiments include a construction having a horizontally-extending layer of fluorocarbon material over a semiconductor construction. Some embodiments include methods of filling openings that extend into a semiconductor construction. The methods may include, for example, printing the material into the openings or pressing the material into the openings. The construction may be treated so that surfaces within the openings adhere the material provided within the openings while surfaces external of the openings do not adhere the material. In some embodiments, the surfaces external of the openings are treated to reduce adhesion of the material.

  • Publication number: 20210020219
    Abstract: Methods, systems, and devices for enabling fast pulse operation are described. A threshold voltage of a selection component and a requisite duration for a voltage applied to a selection component to reach a threshold voltage in response to a voltage generated by an external source may be determined. The threshold voltage may correspond to a voltage at which the selection component is configured to release electric charge. A voltage may then be generated and applied to an access line that is in electronic communication with the selection component and a memory cell for at least the requisite duration. Electric charge may be stored at the selection component during the requisite duration and transferred to memory cell after the requisite duration.
