Abstract
Ovonic Threshold Switch (OTS) device is most popular switching device in PRAM. There are many OTS device research; however, it is hard to make reasonable OTS device which uses a circuit simulation and real device. In this work, we studied the OTS device emulation circuit, which can follow OTS characteristic, especially snapback current using 0.18 μm CMOS technology. This circuitry composes snapback current generator, cut off switch and output driver. Snapback current generator can make the current level up to 300 μA.
