The present disclosure relates to a method comprising the steps of defining a minimum number of parity cells for storing parity data, the minimum number of parity cells corresponding to a minimum Error Correction Code (ECC) correction capability, defining a maximum number of parity cells for storing the parity data, the maximum number of parity cells corresponding to a maximum ECC correction capability, storing payload content in a plurality of memory cells of a memory array, and, based on a current status of the memory cells storing the payload, selecting a number of parity cells to be used for storing the parity data between the minimum number and the maximum number. The payload is stored in at least part of the parity cells which are not selected to store parity data. Related memory devices and systems are also herein disclosed.
