Multi-Bit-per-Cell a-IGZO TFT Resistive-Switching Memory for System-on-Plastic Applications

Abstract

We reported a novel flexible nonvolatile memory using complete logic-compatible a-IGZO TFTs fabricated at room temperature. The memory device utilized localized and independent resistive switching for high-density two-bit-per-cell and multi-bit-per-cell operations. Combining low-temperature fabrication, low-cost integration, high bit-density, and excellent flexible memory characteristics, this device shows promise for future system-on-plastic applications.
