  • Publication number: 20260303436
    Abstract: Various methods and processes, apparatuses or systems, and media for prioritizing alerts and identifying significant alerts that relate to security events in order to mitigate an alert-fatigue phenomenon, are disclosed. The method includes: receiving a first alert; providing the first alert to a model that is trained by using historical data relating to prior alerts; using the model to generate a prioritization score that relates to the first alert; determining, based on the prioritization score, whether to prioritize the first alert by placing the first alert at a top portion of a queue of alerts received within a predetermined time frame; and transmitting an updated version of the queue of alerts that includes the first alert in conjunction with the first prioritization score.

  • Patent number: 10049759
    Abstract: Technology for an apparatus is described. The apparatus can include a memory controller with circuitry configured to initiate a program verify sequence to verify data written to a non-volatile memory (NVM). The program verify sequence can have one or more program verify levels that each correspond to memory cells in the NVM for which written data is being verified. The memory controller can detect an approximate percentage of memory cells for each program verify level in which data is successfully written. The memory controller can determine to skip subsequent program pulse verification checks in one or more program verify levels when the approximate percentage of memory cells in which data is successfully written is less than a defined threshold.
