A new set of programmable elements (PEs) using a new non-volatile device for use with routing switches and logical elements within a field-programmable gate array (FPGA) is described. The PEs have small area, can be combined with components that use low operational voltage on the same CMOS logic process, are non-volatile, enable the use of fast thin-oxide pass transistors, and are reprogrammable. A novel non-volatile flip-flop for use within the logical elements is presented as well. In
