Abstract
In this work, we develop a model for a threshold switching device to be used in the context of an analog CAM design. For this, we tune and optimize a two-terminal hysteretic device model that relies on a state variable to capture proper behavior in different operating conditions. It satisfies a 1 mV/decade ON switching slope. We study the model sensitivities in the context of device charging a capacitor and an analog CAM cell switching between match and mismatch states. We also study the impact of variations in the device hold and switching voltage parameters on the analog search interval.
