  • Publication number: 20260127075
    Abstract: A processing device receives operating data associated with one or more storage devices and analyzes the operating data using one or more artificial intelligence (AI) models to generate voltage threshold offsets for memory pages of the one or more storage devices. The processing device applies the generated voltage threshold offsets to read operations to read data from the memory pages. The AI models may be trained using data from other storage systems and can be executed by a storage system controller, by storage device controllers of the storage devices, or by both in a coordinated configuration. The disclosed techniques dynamically adjust voltage thresholds based on current device conditions to improve read accuracy, reduce error rates, and enhance overall system reliability and endurance.

  • Patent number: 12599720
    Abstract: A method of detecting a fault condition in an infusion process, the method includes receiving a programmed flow rate pertaining to a fluid infusion provided by an infusion device; determining, a first weight of an infusion container associated with the fluid infusion provided by the infusion device at a first time; determining a second weight of the infusion container at a second time; determining based on the first weight and the second weight, a determined flow rate of the fluid infusion provided by the infusion device between the first time and the second time. The method includes determining a difference between the determined flow rate and the programmed flow rate. When a magnitude of the difference between the determined flow rate and the programmed flow rate satisfies a predetermined threshold, by the processor: causing an output of the infusion device or the weight sensor to indicate the fault condition.

  • Patent number: 12360850
    Abstract: Aspects of a storage device are provided for handling GBBs with defects between global interconnects and local word lines. The storage device includes a plurality of blocks each including a plurality of word lines, a plurality of interconnects within an interconnect set and between multiple ones of the blocks, volatile memory, and a controller. The controller determines a logical address pattern associated with the multiple ones of the blocks respectively including a program failure, determines whether the logical address pattern is associated with the interconnect set for the multiple ones of the blocks, determines a common word line associated with the program failures in the multiple ones of the blocks, un-marks these blocks as GBBs, and refrains from programming the common word line during respective program operations in the multiple ones of the blocks. Thus, blocks may be reclaimed, defective word line(s) isolated, and likelihood of read-only modes reduced.
