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 counter clearance are described. In example implementations, a memory device includes a memory array having multiple rows. The memory device also includes multiple usage-based disturbance counters that are associated with the memory array. The memory device further includes logic that performs a refresh operation on a row of the multiple rows responsive to a refresh command. The logic also clears a usage-based disturbance counter of the multiple usage-based disturbance counters responsive to the refresh command. Here, the usage-based disturbance counter stores a quantity of accesses to the row of the multiple rows. This can reduce a frequency of performing usage-based disturbance mitigation procedures that would otherwise be applied to the multiple usage-based disturbance counters, thereby saving power and avoiding denial-of-service periods with the memory array.

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.
