FPGA based on integration of memristors and CMOS devices

This paper introduces a novel CMOS-memristor hybrid reconfigurable architecture, mFPGA. Different from the existing crossbar-based CMOS-memristor architectures, mFPGA mainly consists of lTlM-like structures that can be fabricated by using a CMOS-compatible process. These devices can efficiently establish FPGA block memories. More importantly, novel CMOS-memristor routing switches are developed to replace the CMOS routing switches to achieve significant density enhancement and power reduction. The simulation results demonstrate that 2D and 3D mFPGAs provide at least a 2X to 3X overall improvement in terms of area reduction, and a 20% lower power consumption, compared with corresponding CMOS FPGA architectures.
