Abstract

This paper presents a novel compact delay model of Ovonic Threshold Switch (OTS) devices that works efficiently for circuit simulations. The internal state variable of the two terminal devices is estimated using a delay system that uses a few electrical components related to a suggested equivalent circuit of the device. Finally, we tested the proposed model against measured data from devices fabricated by Western Digital Research.
