Organic electrochemical transistors (OECTs) have recently emerged as a feasible candidate to realize the next generation of printable electronics. Especially, their chemical versatility and the unique redox-based operating principle have provided new possibilities in high-functioning logic circuitry beyond the traditional binary Boolean logic. Here, a simple strategy to electrochemically realize monolithic multi-valued logic transistors is presented, which is one of the most promising branches of transistor technology in the forthcoming era of hyper Moore's law. A vertically stacked heterogeneous dual-channel architecture is introduced with a patterned reference electrode, which enables a facile manifestation of stable and equiprobable ternary logic states with a reduced transistor footprint. The dual-ion-penetration mechanism coupled with ultrashort vertical channel even allows a very-high accessing frequency to multiple logic states reaching over 10 MHz. Furthermore, printed arrays of ternary logic gates with full voltage swing within 1 V are demonstrated.
