A dynamic random access memory based on a conjugated copolymer containing electron-donor and -acceptor moieties

Abstract

Remember this: The conjugated copolymer PFOxPy, which contains both electron-donor and -acceptor groups, exhibits dynamic random access memory behavior in the sandwich structure ITO/PFOxPy/Al (see picture). The device is characterized by low read, write, and erase voltages, a high ON/OFF current ratio (up to 106), stable ON and OFF states under a constant stress of -1 V, and up to 108 read cycles at a read voltage of -1 V.
