A 3-D Crossbar Architecture for Both Pipeline and Parallel Computations

A 3D architecture made up of a CMOS layer combined with stack bipolar memristor crossbar arrays provides an innovative approach to hardware support for utilizing the strength memristors. Memristors have been evaluated implementing broad spectrum applications such as memory, computations, hardware-based security primitives, cryptography, etc., and numerous studies shown that memristors are desirable candidates applications. This paper proposes novel memristive (i.e., built on top substrate) specific focus way connecting layer. The proposed is configurable allows restructuring creating 1D adjustable sizes. enables parallel pipeline computations where data can move or be processed in planes perpendicular stacked arrays. In addition, scalable meaning stacks connected without additional overhead. shows examples full adder, 4-bit look-ahead carry generator, 8-bit multiplexer. Simulations area, delay, power analysis demonstrate behavior circuit.
