Abstract: Apparatuses and techniques for implementing refresh latency indication for refresh operations are described. A memory system may separate memory dies into different ranks. Sending separate refresh commands to each rank congests the command bus. Sending a common refresh command to multiple ranks, on the other hand, causes a large current spike as many dies initiate the refresh operation at the same time. To efficiently prevent the large current spike and thereby lower the costs of a power delivery network, different dies can delay initiation of the refresh commands by different amounts. To do so, a host device can program different dies with different refresh latency indications, which determine lengths of each delay period before starting the refresh operation. The dies can also operate based on an enablement indication that enables the refresh latency mechanism. Staggering the start times of refresh operations can also control current spikes without regard to ranks.

Abstract: Apparatuses and techniques for reporting a notification-type event are described. In an example aspect, a memory device includes a dedicated notification pin for reporting one or more notification-type events to a memory controller. Through the notification pin, the memory device can indicate an occurrence of various notification-type events, one or more of which can be associated with mitigating usage-based disturbance. In contrast to an alert pin, the notification pin enables an operation of the memory controller to continue uninterrupted. In other words, notification-type events that are reported via the notification pin do not need to interrupt an operation of the memory controller. In this way, the notification pin can be used to communicate notifications without degrading performance of the memory controller. Also, with a dedicated notification pin, the memory controller can avoid continuously polling mode registers of the memory device for information, thereby conserving power and temporal resources.

Abstract: Apparatuses and techniques for implementing self-refresh status indications for self-refresh exit are described. To save power, a memory device can control refresh operations, but the memory device is typically unavailable in this self-refresh mode. During self-refresh exiting, the memory device typically remains unavailable for normal array access operations while concluding any refresh operations that are already in progress. Portions of the memory array, however, are usually not performing a refresh operation. To enable a host device to perform read and write operations on these available portions during the self-refresh exit time, the memory device provides an indication of a self-refresh status in example implementations. The indication can be a Boolean variable that pertains to an entire array. Alternatively, the indication can include multiple bits that respectively correspond to multiple portions, such as memory banks or bank groups. In this way, the host device can return to normal operations sooner.

Abstract: Apparatuses and techniques for performing serialized update procedures during a refresh period are described. In example aspects, a memory device performs a normal refresh operation, which refreshes multiple rows simultaneously. The refreshed rows are associated with different refresh sections and different column segments. While refreshing the rows and prior to an end of a refresh cycle time (tRFC), the memory device updates, in a serialized manner, usage-based-disturbance data that is stored within the refreshed rows. In particular, the memory device performs, in series, multiple update procedures, which overwrites values of the usage-based-disturbance data that are stored within the refreshed rows. For example, the multiple update procedures can set values of activation counts that are stored within the refreshed rows to a predetermined value.

Abstract: A value associated with a number of accesses of a word line and a length of said accesses may be stored on said word line. A timer may provide a periodic signal that increments a counter to update the value. The updated value may then be written back to the word line. In some examples, a memory device including the word lines may have a specification that prevents the word line from closing prior to writing the updated value to the word line.

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.

Abstract: Apparatuses and techniques for reporting multiple events associated with mitigating usage-based disturbance are described. In an example aspect, a memory device can report to a memory controller various events associated with mitigating usage-based disturbance. This includes notifying the memory controller of events associated with a first event category and alerting the memory controller of events associated with a second event category. For events associated with the first event category, there can be a smaller risk of an alert condition occurring if the memory controller does not take action. For events associated with the second event category, there can be a larger risk of an alert condition occurring if the memory controller does not take action. By reporting these multiple events by category, the memory device empowers the memory controller to take appropriate action and efficiently manage available resources for mitigating usage-based-disturbance.

Abstract: Apparatuses and techniques for implementing collision avoidance for bank-shared circuitry that supports usage-based disturbance mitigation are described. A memory device includes bank-shared circuitry coupled to multiple banks. The bank-shared circuitry can support usage-based disturbance mitigation. By using the bank-shared circuitry to service multiple banks, the memory device can have a smaller footprint and can be cheaper to manufacture compared to other memory devices with circuitry dedicated for each bank. To avoid conflicts associated with some sequences of commands that may relate to a same bank or different banks and utilize the bank-shared circuitry, the memory controller applies an appropriate timing offset (or delay) between commands. The timing offset allows the memory device time to finish utilizing the bank-shared circuitry for usage-based disturbance mitigation prior to utilizing the bank-shared circuitry in accordance with a subsequent command.
