A Quaternary FPGA Architecture Using Floating Gate Memories

A new quaternary FPGA (QFPGA) architecture based on floating-gate memories is presented and analyzed. Technology scaling has delivered substantial FPGA performance, but consumer demands grow beyond binary circuit capabilities. Non-binary FPGAs have been explored, but previous architectures use non-standard fabrication and optimistic performance analysis. The proposed QFPGA based on floating-gate memories has competitive power performance compared to contemporaries QFPGA architectures from literature when simulated FinFET technology.
