PROBLEM TO BE SOLVED: To provide an FPGA for realizing space-saving of an FeRAM incorporated in the FPGA and the high density of the mounting. SOLUTION: The FeRAM is comprised of a plurality of memory cells M00-Mnn. The memory cell M00 is comprised of an SRAM 4 and the FeRAMs 5-0 to 5-n. The SRAM 4 is comprised of inverters 6, 7 and MOS transistors 8, 9. The FeRAMs 5-0 to 5-n are comprised of only ferroelectric capacitors CO1, CO2. By this, the FeRAMs 5-0 to 5-n do not include a transistor. Accordingly, the space-saving of the FeRAM can be realized and also the high density of the mounting can be realized.
