A memory controller accesses a memory page in a memory block of a storage memory array of a memory device. The memory controller reads memory data stored in the accessed memory page. The memory controller determines a number of error bits associated with the memory data. The memory controller obtains an erase count corresponding to the accessed memory page, the erase count indicating a number of erase operations performed on the accessed memory page. The memory controller determines, from among one or more error threshold values, an error threshold value based at least on the erase count. The memory controller determines a relationship between the number of error bits and the error threshold value. The memory controller triggers a data refresh for the accessed memory block if the relationship between the number of error bits and the error threshold value satisfy a known criterion.
