CMOS Based Ovonic Threshold Switching Emulation Circuitry

초록

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 mu m 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 mu A.
