Abstract
Phase change memory cells including a phase change media can be encoded using a source of energy that is not integral with the memory cell. External sources of energy include thermal heads, such as those used in direct thermal printing or thermal transfer printing and sources of electromagnetic radiation, such as lasers. Such types of phase change memory devices can be associated with substrates that include thermochromic materials or are suitable for thermal transfer printing so that the memory cells can be encoded and print media applied to the substrate using the same source of thermal energy.
