Abstract
A three-terminal Ovonic Threshold Switch (OTS) is used to provide current to a Phase Change Memory Switch (PCMS) cross point array. The current is started by sending a small current into the second terminal of the three-terminal OTS allowing a larger current to flow from the first terminal to the third terminal of the three-terminal OTS. A method of making the three-terminal OTS is also presented.
