determining that a value of a write counter associated with a memory device satisfies a first threshold criterion, wherein the write counter is a global counter indicating a number of write operations to the memory device;

determining that a set of failed bit count statistics corresponding to a plurality of codewords of a memory unit of the memory device satisfies a second threshold criterion; and

responsive to determining that the set of failed bit count statistics corresponding to the plurality of codewords of the memory unit satisfies the second threshold criterion, performing a write scrub operation on the memory unit.
