1. A method, comprising:
determining a count corresponding to a number of operations at a memory location of a memory device;
scheduling a number of maintenance operations for the memory location in response to the count exceeding a first predetermined threshold, wherein the number of scheduled maintenance operations corresponds to an extent by which the count exceeds the first predetermined threshold; and
decreasing the count by an amount that is less than the count in response to executing one or more of the number of scheduled maintenance operations.
