Abstract

A field-programmable-gate-array (FPGA) IC chip includes multiple first non-volatile memory cells in the FPGA IC chip, wherein the first non-volatile memory cells are configured to save multiple resulting values for a look-up table (LUT) of a programmable logic block of the FPGA IC chip, wherein the programmable logic block is configured to select, in accordance with its inputs, one from the resulting values into its output; and multiple second non-volatile memory cells in the FPGA IC chip, wherein the second non-volatile memory cells are configured to save multiple programming codes configured to control a switch of the FPGA IC chip.
