Embodiments of the disclosure are drawn to apparatuses and methods for dynamic column select swapping. A memory may have a number of sets of bit lines organized into column planes. If a set of bit lines associated with a first address in a first column plane is defective, it may be repaired by reassigning the first address to a redundant set of bit lines in a global column redundant (GCR) column plane. If a set of bit lines associated with the first address in a second column plane is also defective, then swap logic of the memory may swap the first address to a second address and assign it to the set of bitlines in the second column plane. The second address may then also be repaired by being reassigned to the GCR column plane.
