  • Publication number: 20250068345
    Abstract: Apparatuses and methods per-row count based refresh target identification. A memory device stores count values associated with the word lines. An aggressor detector circuit stores a maximum of the count values and a row address associated with the maximum count value. Responsive to a targeted refresh signal, the stored count value is compared to a threshold. If the count value has crossed the threshold, then a targeted refresh operation may be performed on one or more refresh addresses based on the stored address, and the count value may be reset.

  • Patent number: 12235353
    Abstract: In various examples, a hazard detection system fuses outputs from multiple sensors over time to determine a probability that a stationary object or hazard exists at a location. The system may then use sensor data to calculate a detection bounding shape for detected objects and, using the bounding shape, may generate a set of particles, each including a confidence value that an object exists at a corresponding location. The system may then capture additional sensor data by one or more sensors of the ego-machine that are different from those used to capture the first sensor data. To improve the accuracy of the confidences of the particles, the system may determine a correspondence between the first sensor data and the additional sensor data (e.g., depth sensor data), which may be used to filter out a portion of the particles and improve the depth predictions corresponding to the object.

  • Patent number: 12233406
    Abstract: Two or more micropipettes are used to increase a microinjection throughput in an automated system for microinjecting adherent cells on a Petri dish. In the system, a motorized stage carrying the Petri dish sequentially visits the cells according to an optimized injection sequence. The sequence is selected by minimizing a total distance traveled by the motorized stage such that each cell is visited once by one of the micropipettes. Using multiple micropipettes advantageously reduces the minimized total distance over using a single micropipette to thereby increase the throughput. The optimized injection sequence is obtained by solving an equality-generalized traveling salesman problem. Each micropipette is mounted on a motorized micromanipulator. The motorized stage and motorized micromanipulators operate coordinately that each micromanipulator goes down or up during movement of the motorized stage to compensate for unevenness between a focus plane and a moving trajectory of the motorized stage.

  • Patent number: 12165687
    Abstract: Apparatuses and methods for row hammer counter mat. A memory array may have a number of memory mats and a counter memory mat. The counter mat stores count values, each of which is associated with a row in one of the other memory mats. When a row is accessed, the count value is read out, changed, and written back to the counter mat. In some embodiments, the count value may be processed within access logic of the counter mat, and a row hammer flag may be provided to the bank logic. In some embodiments, the counter mat may have a folded architecture where each sense amplifier is coupled to multiple bit lines in the counter mat. The count value may be used to determine if the accessed row is an aggressor so that its victims can be refreshed as part of a targeted refresh.

  • Publication number: 20240363191
    Abstract: Apparatuses and techniques for implementing usage-based disturbance (UBD) counter repair are described. In example implementations, a memory device includes multiple memory rows, multiple corresponding UBD counters, a register, and a spare UBD counter. If a UBD counter is faulty, logic can substitute the spare UBD counter. To do so, the logic can store a row address corresponding to the faulty UBD counter in the register. The logic can increment a value in the spare UBD counter responsive to a row activation corresponding to the stored row address. A mitigation procedure on a row that may be affected by the activation can be performed based on the value. A host device can control, at least partially, the UBD counter repair process. In these manners, a repair of a faulty UBD counter can be accomplished faster and/or with fewer resources as compared to replacing a memory row and corresponding UBD counter.

  • Publication number: 20240355366
    Abstract: A semiconductor device may include a voltage threshold compensation (VTC) sense amplifier configured to amplify signals read from memory cells to recognizable logic levels. The VTC sense amplifier may equalize threshold voltages of transistors at the sense amplifier during a compensation phase before sensing a memory cell. The compensation phase may be delayed or extended in duration by an amount based on a combination of currents that are proportional to absolute temperature (PTAT) and zero to absolute temperature (ZTAT), or PTAT and complementary to absolute temperature (CTAT). Different combinations of PTAT and ZTAT currents, or PTAT and CTAT currents, may correspond to different temperature slopes. The semiconductor device may choose from the different temperature slopes to achieve different delays for given temperatures.
