A simple and advanced neural circuit element by using an SOI insulated-gate pn junction device

Neural logic devices and circuits have been extensively studied, and recently, a /spl nu/MOS transistor and its logic circuits were proposed (Shibata and Ohmi, 1991). However, a /spl nu/MOS transistor which shows a neuron-like operation (sum of products) does not reflect a synaptic operation flexibly. The author has previously proposed a synaptic logic element by using an SOI insulated-gate p-n junction device called a lubistor (Omura, Appl. Phys. Lett. vol. 40, vol. 6, pp. 528-9, 1982), and recently demonstrated important functions (Omura, Ext. Abstr. of Int. Conf. on Solid State Dev. and Mat., pp. 140-1, 1997). This paper describes a new, simple, advanced neural circuit element and simulation results of circuit operations.
