Abstract
Innovative Non-Volatile Look-Up-Table (NV-LUT) has been constructed by Single Gate Logic Non-Volatile Memory (SGLNVM) devices processed with the standard CMOS logic process. One of a pair of complementary SGLNVM devices is always programmed to the high threshold voltage state and the other remains in the low threshold voltage state. By applying digital voltage rail (VDD and VSS) to the input nodes of the pair of complementary SGLNVM devices, the output node of the pair of complementary SGLNVM devices outputs digital signals according to its configuration. The NV-LUT outputs digital signals from a plurality of pairs of complementary SGLNVM devices through a digital switching multiplexer. The NV-LUT is a good substitution for SRAM based LUT commonly used in Field Programmable Gate Array (FPGA).
