High-performance TiN/TaOx/TiN selectors with short-term memory characteristics

High-performance TiN/TaOx/TiN selectors with short-term memory characteristics

We present TiN/TaOx/TiN device structure showing varistor and short-term memory (STM) characteristics that could be useful for selector applications and temporal processing in one-selector one-RRAM (1S1R) architectures. The devices show high selectivity (103) and excellent endurance (one million cycles) and can sustain high-voltage stress (103s). The varistor behavior persists with device scaling down to 2.25 μm2 and thickness as thin as 2 nm. Moreover, the device exhibits a volatile switching behavior under pulse programming that could offer an additional analog output from single-digital input feed into the integrated 1S1R arrays.

Abstract

We present TiN/TaOx/TiN device structure showing varistor and short-term memory (STM) characteristics that could be useful for selector applications and temporal processing in one-selector one-RRAM (1S1R) architectures. The devices show high selectivity (103) and excellent endurance (one million cycles) and can sustain high-voltage stress (103s). The varistor behavior persists with device scaling down to 2.25 μm2 and thickness as thin as 2 nm. Moreover, the device exhibits a volatile switching behavior under pulse programming that could offer an additional analog output from single-digital input feed into the integrated 1S1R arrays.
