A method for accessing a memory comprising a first set of bit columns, a second set of bit columns, and a redundant set of bit columns, wherein any one of the redundant set of bit columns can be substituted for one of the first set of bit columns or one of the second set of bit columns and wherein each of the bit columns can receive a read voltage or a write voltage, is provided. The method includes during a write operation to the first set of bit columns, providing the write voltage to one of the redundant set of bit columns, if the one of the redundant set of bit columns has been substituted for one of the first set of bit columns, otherwise providing the read voltage to the redundant set of bit columns.
