Until now, any computer calculation is hampered by the basic computer architecture: All data has to be shifted back and forth between fast but volatile random access memory (RAM) and the non-volatile but slow hard drive. The ultimate data memory combines non-volatile behaviour together with fast read and write access and a high integration density. Great potential lies in resistively switching memory cells, which consist of a conductor-insulator-conductor structure. By applying appropriate voltages, the cell resistance can be switched between at least two resistance states, corresponding to �??0�?� and �??1�?�. The non-volatile resistive memory offers fast operation speed and low power consumption. We report inkjet printing of resistive memory cells, which provides two additional advantages: Firstly, the printing at ambient conditions makes cleanroom environment obsolete and considerably lowers the production costs. Secondly, printing on flexible films opens the door to the up-and-coming field of printed electronics, where resistive memory could be integrated in flexible printed circuits. We use a standard FujiDimatix® 2831 inkjet printer for the printing of all 3 layers of our memory cells. For the conducting electrodes we use organic polymers and various commercial as well as in-house synthesized metal nanoparticle inks. The insulator layer consists of a printed methylsiloxane polymer. As a substrate we use rigid silicon wafers and flexible polyimide films. The cells show the potential for multi-bit data storage. With switching voltages below 3 V and switching currents in the nanoampere regime, we already see a substantially lower power consumption compared to flash technology.
