  • Publication number: 20250131955
    Abstract: Embodiments of the disclosure are drawn to apparatuses and methods for row hammer counter resets. Repeated access to an aggressor word line may cause increased data degradation in nearby victim word lines of the memory. The access count value of a given word line may be stored in counter memory cells positioned along that word line. The count values may be randomly or pseudo-randomly initialized. In some examples, a memory device may utilize residual charges that are present on the counter cells during start-up to initialize the counter memory cells. In some other examples, a memory device may utilize threshold voltage compensation (VtC) settings at start-up to initialize the counter memory cells. In some other examples, a memory device may utilize a combination of the residual charges that are present on the counter cells and VtC settings on start-up to initialize the counter memory cells.

  • Publication number: 20250111045
    Abstract: Memory devices direct refresh management (DRFM) attack identification. A DRFM logic circuit receives DRFM aggressor address and compares it to a previous DRFM aggressor address. If there is not a match, then a DRFM operation is performed. If there is a match, then the DRFM operation may be skipped. This may prevent repeated DRFM operations from being performed on a same DRFM aggressor address.

  • 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.

  • Patent number: 12155822
    Abstract: A system and method for video compression divides colors of all pixel points of a target video frame into R, G, and B values, and all pixels are placed in a three-dimensional coordinate system to establish a correspondence between each pixel point and the coordinate position. Fuzzy recombination and division are performed on all pixel blocks and pixel points with similar RGB values are divided into pixel blocks to obtain a first target pixel block. Pixel blocks with same RGB values but with coordinates which are not close to the first target pixel block are extracted and divided to obtain a second target pixel block. An area enveloping the second target pixel block is extracted, and vector changes of all dynamic pixel points on the enveloping line are traversed and analyzed to determine a minimum compression change block for compression process.

  • Publication number: 20240379147
    Abstract: Apparatuses and techniques for implementing aspects of proactive usage-based disturbance mitigation based on resource availability are described. In an example aspect, usage-based disturbance circuitry of a memory device performs usage-based disturbance mitigation based on multiple criteria. A primary criterion is associated with normal usage-based disturbance mitigation and can enable the memory device to balance power consumption with usage-based disturbance mitigation. At least one secondary criterion is less strict compared to the primary criterion. While a resource is available, the usage-based disturbance circuitry can proactively mitigate usage-based disturbance based on activated rows that satisfy the secondary criterion but don't yet satisfy the primary criterion. With these preemptive measures, the usage-based disturbance circuitry can reduce a probability of a waterfall event causing a denial-of-service (DOS) situation while the resource is available.

  • Publication number: 20240379148
    Abstract: Apparatuses and techniques for implementing aspects of a time-varying threshold for usage-based disturbance mitigation. In an example aspect, usage-based disturbance circuitry of a memory device utilizes a threshold that varies over time for detecting conditions associated with usage-based disturbance. By utilizing the time-varying threshold, the usage-based disturbance circuitry can reduce a probability of a waterfall event causing a denial-of-service (DOS) situation. In particular, the time-varying threshold can spread out the refreshing of rows over a longer time period. This enables the memory device to have sufficient resources to service other memory requests while also mitigating usage-based disturbance. In example implementations, the threshold is at least partially randomized, which can make it challenging for a malicious actor to identify and overcome the usage-based disturbance mitigation techniques.
