Abstract

We demonstrate a novel VO2 based edge-triggered (ET) three-terminal Mott switch that leverages the displacement current induced by the switching of the gate voltage pulse to trigger an IMT in the VO2 channel. The design overcomes a long-standing challenge of realizing a three-terminal VO2 switch due to the absence of field-effect induced IMT in VO2. The ET Mott switch also enables isolation between the input the output (at steady state), and facilitates reduction in the effective trigger voltage in comparison to the two-terminal configuration. We show using simulations that these properties can be exploited to enable a BEOL-compatible 3T selector for MTJ-based cross-point memory, showing 3.4× higher cell TMR, as well as 45% 40% lower sneak-path current power, respectively.
