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.
