Abstract
Embodiments of the present disclosure provide methods, devices, modules, and systems for non-volatile multilevel memory cell data retrieval with data read of reference cells. One method includes programming at least one data cell of a number of data cells coupled to a selected word line to a target data threshold voltage (Vt) level corresponding to a target state; programming at least one reference cell of a number of reference cells coupled to the selected word line to a target reference Vt level, the number of reference cells interleaved with the number of data cells; determining a reference state based on a data read of the at least one reference cell; and changing a state read from the at least one data cell based on a change of the at least one reference cell.
