Abstract
A page copy operation such as copy back programming is performed between a source page of the memory array and a destination page of the memory array in different segments. The segments divide the columns of the main array and the set of redundant columns of the redundant array into, for example, sets of rows. The copy back programming transfers data from a part of the source page in the redundant array to a part of the destination page in the main array, and transfers data from a part of the source page in the main array to a part of the destination page in the redundant array.
