Abstract

The logic blocks of Field Programmable Gate Array (FPGA) basic unit are mainly composed of Look-Up-Tables (LUTs). The traditional LUTs use the static random access memory (SRAM), which causes FPGA reach the limitation in term of the density, speed, and configuration overhead. In this paper, a novel nanometer memristor-based LUT (NMLUT) is composed of memristors, MOS field effect transistors, decoders, resistors. A three-input NMLUT and a four-input NMLUT circuits are investigated. Moreover, an adder is used to verify the practicality of NMLUT circuit. The proposed NMLUT circuit can implement some combinational logic functions through specific configuration and it is better in data transmission and data storage than the traditional LUT. Since NMLUT circuit is compatible with the mainstream circuit in the FPGA, it can effectively solve the limitations of the field FPGA. The correctness of the results is verified in PSPICE software.
