Researchers from the Munich University of Applied Sciences in Germany managed to produce RRAM (CBRAM) devices using a standard inkjet printer (FujiFilm Dimatix DMP 2831) without any additional processing steps such as electroplating or lithography. The researchers say that the memory devices have a performance comparable to regular RRAM devices created in a clean-room process.

To create these memory cells, the researchers used three different inks: silver nanoparticles, spin-on-glass (liquid glass) and PEDOT:PSS. The silver created the conductive layer, the spin-on-glass was the insulating layer and the PEDOT:PSS was also used to create conductive layers. The memory device was printed on a cheap and flexible plastic foil.
