Ge-based non-volatile memories

With the emerging of Internet of Things, low power memories with the fair performance are attracting more and more attention in both industry and academia. Specially, novel non-volatile memory technology plays the key role in chips pursuing a tradeoff among area, energy, storage and speed. Recently, lots of reports focus on a new non-volatile device technology which is named memdiode (MD) using germanium material. In this paper, we will review the concept of MD and its applications in conventional non-volatile resistive switching memory devices, ternary content addressable memory, and NAND-like flash memory devices.
