  • Patent number: 11361834
    Abstract: A memory device comprising control circuitry configured to apply a first program voltage to a selected word line, wherein a first subset of memory cells of the selected word line, that correspond to a first set of data states, are inhibited from being programmed with the first program voltage, and wherein the first program voltage is applied to a second subset of memory cells corresponding to a second set of data states. The control circuitry is further configured to cause a first voltage of the selected word line to discharge to a second voltage level corresponding to a second program voltage such that the second program voltage is applied to at least the first subset of memory cells. The control circuitry is further configured to perform a verify operation to verify whether the first subset of memory cells and the second subset of memory cells have completed programming.

  • Publication number: 20220179606
    Abstract: A historian interface system provides a graphical representation of tags that represent attributes of a continuous process. A historian system stores the tags and metadata values describing the tags. A display device coupled to the historian system via a communication network displays graphical representations of the tags via display panels and receives selections of the tags. The historian system contextualizes selected tags based on the metadata values describing the selected tag and determines an optimal visualization scheme for the selected tags. The display device displays graphical representations of values of the tags and dynamically determines optimal grouping of the tags based on properties of the display device.

  • Patent number: 11347684
    Abstract: A new snapshot of a storage volume is created by instructing computing nodes to suppress write requests. An orchestration layer implements a multi-role application that is provisioned with virtualized storage and computation resources. A snapshot of the application may be created and used to rollback or clone the application. Clones snapshots of storage volumes may be thin clones. An application may use multiple orchestration approaches and objects of the multi-role application may be discovered and added to an application definition. The application definition may be used to create snapshots of the application and perform operations using the snapshots. Rolling back may include deleting objects other than PVCs, followed by rolling back storage volumes mounted to the PVCs, followed by recreating objects according to an application snapshot. PVCs created by a custom resource may be deleted along with the custom resource with the PVCs being recreated before recreating the custom resource.
