  • Publication number: 20220036927
    Abstract: Some embodiments include an integrated assembly having a memory array, and having digit lines extending along a first direction through the memory array. Insulative spacers are along sidewalls of the digit lines. The insulative spacers extend continuously along the digit lines through the memory array. Conductive regions are laterally spaced from the digit lines by intervening regions. The conductive regions are configured as segments spaced apart from one another along the first direction. The intervening regions include regions of the insulative spacers and include void regions adjacent the regions of the insulative spacers. The void regions are configured as void-region-segments which are spaced apart from one another along the first direction by insulative structures. Storage-elements are associated with the conductive regions. Some embodiments include methods of forming integrated assemblies.

  • Patent number: 11170012
    Abstract: A method and system for determining a session count is described. At a user interface a request is received to determine a session count for a time period. Based on the received request, the session count is determined based on unique new session counts corresponding to one or more time intervals included in the time period and carry forward session count corresponding to an initial time interval included in the time period. Finally, the determined session count is displayed at the user interface.

  • Publication number: 20210224256
    Abstract: The disclosure relates to decentralized management of nodes in a blockchain network. Participants may agree to a consensus rules and implement them as smart contracts. For example, one rule may specify that a node will accept a change proposal only when its local policies and/or data allow it to implement the change. A smart contract may implement this rule and deploy it across the blockchain network for each node to follow. Other participants, through their nodes, may propose changes to the blockchain network, and each node may consult its copy of the smart contract to determine whether to vote to approve the change request and apply the change request locally.

  • Publication number: 20210183865
    Abstract: Systems, apparatuses, and methods related to semiconductor structure formation are described. An example apparatus includes a first trench and a second trench formed in a semiconductor substrate material, where the first and second trenches are adjacent and separated by the semiconductor substrate material. The apparatus includes a metallic material formed to a first height in the first trench that is less than, relative to the semiconductor substrate material, a second height of the metallic material formed in the second trench and a polysilicon material formed over the metallic material in the first trench to a first depth greater than, relative to the semiconductor substrate material, a second depth of the polysilicon material formed over the metallic material in the second trench. The greater first depth of the polysilicon material formed in the first trench reduces transfer of charge by way of the metallic material in the first trench.
