Inkjet printing of all-polymer non-volatile rewritable memories was demonstrated. A polymeric ferroelectric material sandwiched between two electrically conductive layers formed the memory cell. Inkjet printing of the electrodes was performed with PEDOT-PSS and the active layer was printed with a ferroelectric polymer. Both fluids were modified for high quality jetability in Xaar's XJ126 binary printheads. The test device contained memory arrays of up to 100 bit with a design rule of 200μm wide electrode lines and 1mm line spacing. A pinhole-free ferroelectric layer of 120nm thickness allowed switching of the memory devices at voltages below 20V within 1ms. Large signal-to-noise ratios were recorded even after 10⁵ read-write cycles. Target areas for this technology are low-density memories on flexible plastic substrates or on special papers. Application areas are tag memories, anti-counterfeiting and smart packaging.
