A method of controlling data includes, with respect to non-volatile memory cells connected to bit lines corresponding to a first bit line group, first controlling data written to the non-volatile memory cells by varying a control voltage, and, with respect to non-volatile memory cells connected to bit lines corresponding to a second bit line group, second controlling data written to the non-volatile memory cells by varying a control voltage. The controlling may include reading or verifying. Before verification, the method may include writing data to the non-volatile memory cells.
