Abstract: 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.
