Emerging memory selector devices

Selector devices are critical components in functional crossbar arrays of emerging nonvolatile memories. Both nonlinearity and asymmetry in device characteristics may enable device selection functions. A broad range of two-terminal devices are developed as selector; however, most of them still face great challenges to meet the performance requirements. Simulation of crossbar array characteristics based on selector device models and array design parameters help to assess selector device options and technology/design tradeoffs.
