Embodiments of the present disclosure provide methods, devices, modules, and systems for reading non-volatile memory cells. One method includes programming a number of memory cells coupled in series between a first and second select gate transistor where edge cells are coupled adjacent to the select gate transistors and non-edge cells are coupled between the edge cells. The method includes programming a non-edge cell within a first threshold voltage (Vt) distribution. The method also includes programming an edge cell within a second Vt distribution, wherein the first and second Vt distributions correspond to a same one of a number of data states, and wherein the second Vt distribution is different than the first Vt distribution for at least one of the number of data states.
