A memory which has memory cells with first and second orientations also has reference cells with first and second orientations. When a memory cell with the first orientation is selected, an output of a reference cell with the first orientation is compared to that of the selected cell with the first orientation. When a memory cell with the second orientation is selected, an output of a reference cell with the second orientation is compared to that of the selected cell with the second orientation.
