  • Publication number: 20210057021
    Abstract: Embodiments of the disclosure are drawn to apparatuses and methods for analog row access hacking. A plurality of unit cells are provided, each of which contains one or more analog circuits used to track accesses to a portion of the wordlines of a memory device. When a wordline in the portion is accessed, the unit cell may update an accumulator voltage, for example by adding charge to a capacitor. A comparator circuit may determine when one or more accumulator voltages cross a threshold (e.g., a reference voltage). Responsive to the accumulator voltage crossing the threshold, an aggressor address may be loaded in a targeted refresh queue, or if the aggressor address is already in the queue, a priority flag associated with that address may be set. Aggressor addresses may be provided to have their victims refreshed in an order based on the number of set priority flags.

  • Publication number: 20210043257
    Abstract: In some embodiments, the present disclosure relates to a method, comprising the performing of a reset operation to a resistive random access memory (RRAM) cell. A first voltage bias having a first polarity is applied to the RRAM cell. An absolute value of the first voltage bias is greater than an absolute value of a first reset voltage. The application of the first voltage bias induces the RRAM cell to change from a low resistance to an intermediate resistance greater than the low resistance. A second voltage bias having a second polarity oppose to the first polarity is then applied to the RRAM cell. An absolute value of the second reset voltage is less than an absolute value of the second voltage bias and less than the absolute value of the first reset voltage. The application of the second voltage bias induces the RRAM cell to have a high resistance.

    Abstract: Embodiments are directed to monitoring network traffic using NMCs that may be arranged to provide scores based on threat assessments associated with anomaly classes such that the anomaly classes may be associated with types of anomalous activity. NMCs may employ the anomaly classes, the scores, characteristics of the anomaly classes, or the like, to determine triage models. The NMCs may modify the scores based on the triage models or archival information associated with the anomaly classes. The NMCs may associate the modified scores with the anomaly classes. In response to detecting anomalous activity, the NMCs may provide other scores based on the anomalous activity and provide a report that includes the other scores to a user.
