Associative memory, considered as the ability to link unrelated objects, is the most appealing
behaviour found in both biological and artificial neural networks. Here we for the first time proposed
a three terminal phase-change based nanoscale device where associative memory can be theoretically
achieved according to the developed electro-thermal model. Compared with the conventional
neural networks circuit, the designed device allows for an exemption from a large number of circuit
elements, and thus exhibits an exciting potential for ultra-high integration density and super-fast response
speed. The simulation results opens up a novel route to imitate the complex mechanism of the
biological neural networks, thus rendering phase-change materials a promising contender for the key
components in next-generation neuromorphic system.
