Emerging crossbar-based hybrid nanoarchitectures for future computing systems

This tutorial paper discusses and analyzes different hybrid nanoarchitectures that are structured using crossbar arrays. Such nanoarchitectures are likely to be used for building future computing systems. The hybrid CMOS/nanodevice architectures leverage the advantage of CMOS maturity and potentials in nanodevice (e.g. high density, low power consumption, reduced manufacturing costs, new functionality, etc.), to aid their mission in increasing the performance better than current CMOS-based architectures. We first describe the concept of crossbar-based nanoarchitecture and then classify the nanoarchitectures into two distinct structures; two-dimensional structures and three-dimensional structures. Subsequently, a detail analysis of each structure is presented including e.g., advantages in terms of area and performance over CMOS-based circuits. Finally, the most promising crossbar-based hybrid nanoarchitecture is suggested.
