Memory programming devices include a print head that moves across a substrate to deposit memory material on the substrate to form an array of memory cells and programming circuitry coupled to the print head so that the programming circuitry moves across the substrate along with the print head and that, for individual memory cells of the array, is positioned proximate the individual memory cell and writes data to the individual memory cell. Memory programming methods include depositing memory material above a first portion of an electrically conductive bitline printed on a substrate to form a memory cell and using programming circuitry positioned proximate the memory cell, storing data in the memory cell by altering a characteristic of the memory cell, the characteristic remaining altered after the programming circuitry is moved away from the memory cell.
