Patent number: 12260896Abstract: Methods, apparatuses, and systems related to operations for memory process feedback. A controller can monitor memory activities, such as processes, identify row hammer aggressors, and perform mitigating steps to the row hammer aggressors. The controller may have a table of addresses of row hammer aggressors and perform operations of tracking row hammer aggressors. The controller can determine whether the number of aggressors reaches a threshold. When the number of aggressors reaches the threshold, the controller can send a message with the aggressor addresses to the operating system. The operating system can perform mitigating steps to the row hammer aggressors. In some embodiments, the controller may identify the row hammer aggressors and inject poisoned data into the process to mitigate the row hammer aggressors.Type: GrantFiled: October 13, 2022Date of Patent: March 25, 2025Assignee: Micron Technology, Inc.Inventor: Sujeet Ayyapureddi

Publication number: 20250094262Abstract: Apparatuses and techniques for implementing usage-based-disturbance alert signaling are described. The technology allows usage-based-disturbance (UBD) alerts to be externally communicated from a memory device without a dedicated external interface. Rather, UBD alerts are combined with memory error/alert signals and communicated on a shared alert-related interface. UBD tracking occurs at the memory bank level, with corresponding independent UBD alert signals. These signals are efficiently combined to generate an overall UBD alert. A temporary backoff signal is generated when an overall UBD alert is sent. The backoff signal ensures requisite external timing parameters are met while allowing the individual memory banks to generate persistent UBD alerts.Type: ApplicationFiled: July 29, 2024Publication date: March 20, 2025Applicant: Micron Technology, Inc.Inventors: Yang Lu, Victor Wong, Donald Morgan
