Mitigating slow read disturb in a memory sub-system

Abstract

Disclosed is a system that comprises a memory device and a processing device, operatively coupled with the memory device, to perform operations that include, receiving a read request to perform a read operation on a block of the memory device; determining whether an entry corresponding to the block is stored in a data structure associated with the memory device; responsive to the entry being stored in the data structure, incrementing a counter associated with the block to track a number of read operations performed on the block of the memory device; resetting a timer associated with the block to an initial value, wherein the timer is to track a period of time that elapses since the read operation was performed on the block of the memory device; determining that the counter and the timer satisfy a first criterion; and responsive to determining that the counter and the timer satisfy the first criterion, removing the entry corresponding to the block from the data structure associated with the memory device.
