A resistive memory cell employs a photoimageable switchable material,
which is patternable by actinic irradiation and is reversibly switchable
between distinguishable resistance states, as a memory element. Thus, the
photoimageable switchable material is directly patterned by the actinic
irradiation so that it is possible to fabricate the resistive memory cell
through simple processes, and avoiding ashing and stripping steps.
