    摘要: A data holding device according to the present invention includes a loop structure portion LOOP for holding data using a plurality of logic gates (NAND3 and NAND4) connected in a loop, a nonvolatile storage portion (NVM) for storing in a nonvolatile manner the data held in the loop structure portion (LOOP) by using the hysteresis characteristics of ferroelectric elements, a circuit separating portion (SEP) for electrically separating the loop structure portion (LOOP) and the nonvolatile storage portion (NVM), and a set/reset controller (SRC) for generating a set signal (SNL) and reset signal (RNL) based on data stored in the nonvolatile storage portion (NVM), wherein the plurality of logic gates are each set and reset to an arbitrary output logic level in accordance with the set signal (SNL) and reset signal (RNL).
