    摘要: A ferroelectric memory device of the present invention includes a memory cell array in which memory cells are arranged in a matrix having first signal electrodes, second signal electrodes arranged in a direction intersecting the first signal electrodes, and a ferroelectric layer disposed at least in intersection regions between the first signal electrodes and the second signal electrodes, and a peripheral circuit section for selectively writing information into or reading information from the memory cell. The memory cell array and the peripheral circuit section are formed in different layers. The peripheral circuit section is formed in a region outside the memory cell array.
