Abstract
Methods for improving the net remnant polarization of a polymer memory cell are disclosed. In one embodiment, the polymer material is heated above the Curie temperature of the polymer material, and the domains of the polymer material are aligned with an externally applied electric field.

A method comprising:
- heating a ferroelectric polymer comprising a polymer material formed on a substrate to a temperature at least as high as a Curie temperature of the polymer material;
- exposing the polymer material to an external electrical field aligning a plurality of domains of the polymer material in a direction relative to a surface of the substrate;
- and
- cooling the temperature of the polymer while maintaining the alignment of the domains of the polymer material.
