Towards printable organic thin film transistor based flash memory devices

The implementation of plastic electronic solutions to large area displays, disposable sensor arrays, radio-frequency identification tags (RFIDs), and various smart packaging devices necessitate the development of organic memories that are solution-processable and readily integrated with the transistors for digital logic. This article highlights recent research progress made towards organic memory transistors based on charge trapping and focuses on the principles and materials (namely, nanoparticles and polymer electrets) for these devices. The challenges and prospects of charge trapping memories are also discussed.
