Memory with deterministic worst-case row address servicing, and associated systems, devices, and methods

Abstract

Memory with deterministic worst-case row address servicing is disclosed herein. A method of the present technology comprises (1) updating a counter value corresponding to a memory row of a memory device in response to detecting activation of the memory row; (2) comparing the updated counter value to a worst-case count value; and (3) in response to determining that the updated counter value is greater than the worst-case count value, setting the worst-case count value equal to the updated counter value and storing a memory row address of the memory row as a worst-case memory row address. The counter value can be one of a plurality of counter values, each counter value (a) corresponding to a respective memory row and (b) configured to track a number of activations of the respective memory row. The method can further comprise performing a row disturb refresh operation using the worst-case memory row address.
