Abstract
The status of emerging non-volatile memories (NVMs) is reviewed, including PCM, STT-MRAM, and RRAM. RRAMs are classified in terms of switching materials (e.g., TMO, solid-state electrolyte) and conductive path (filament or bulk). In particular, the structure and large-scale realization of CBRAM (conductive-bridge RRAM) are described.The identification of RRAM switching mechanisms involves electro-thermal-chemical process, and is statistical in nature. Kinetic Monte-Carlo (KMC) is the suitable tool for this purpose. An in-house developed KMC code, both 2D and 3D, is discussed, along with its application to a low-power 3-terminal RRAM.Finally, compact models for RRAM used in the circuit simulation are briefly introduced.
