1. A system, comprising:
a memory array comprising a plurality of memory cells; and
a controller coupled to the memory array, the controller to perform operations comprising:
determining, based on a Production State Awareness (PSA) information, whether the memory array operates in a field environment;
responsive to determining that the memory array operates in the field environment, identifying a plurality of address ranges referencing respective sets of memory cells of the memory array, wherein each address range is associated with a respective memory access operation counter reflecting a number of memory access operations that have been performed with respect to a corresponding set of memory cells;
identifying, among the plurality of address ranges, an address range associated with a maximum value of a corresponding memory access operation counter; and
causing a media management operation to be performed with respect to a set of memory cells referenced by the identified address range.
