Abstract
A data storage device includes a memory and a controller and may perform a method that includes updating, in a controller of the data storage device, a value of a particular write/erase (W/E) counter of a set of counters in response to an erase operation to a particular region of the non-volatile memory that is tracked by the particular W/E counter and that includes a storage element that is tracked by a particular cell erase counter of the set of counters. The method includes, in response to the value of the particular W/E counter indicating that a count of erase operations to the particular region satisfies a first threshold, initiating a remedial action to the particular region of the non-volatile memory at least partially based on the value of the particular cell erase counter.
