Abstract

The invention relates to a write-once read-many memory element (1), or an assembly thereof, which comprises a substrate on which electrodes are provided and between which a layer is sandwiched, which memory element includes a conjugated polymer or oligomer as well as a dopant. This memory element can be written by temporarily applying a sufficiently high voltage to the electrodes so that the electroconductivity of the layer is permanently reduced.
