Methods for detecting and mitigating memory media degradation and memory devices employing the same

Abstract:

Memory devices, system, and methods for operating the same are provided. The memory device can comprise a non-volatile memory array and control circuitry. The control circuitry can be configured to store a value corresponding to a number of activate commands received at the memory device, update the value in response to receiving an activate command received from a host device, and trigger, in response to the value exceeding a predetermined threshold, a remedial action performed by the memory device. The control circuitry can be further configured to store a second value corresponding to a number of refresh operations performed by the memory device, update the second value in response to performing a refresh operation, and trigger, in response to the value exceeding a second predetermined threshold, a second remedial action performed by the memory device.
