Abstract
A semiconductor memory device has a plurality of memory cells, each having a ferroelectric memory capacitor, arranged in a matrix formation in rows and columns. A read-out device is associated with each row for reading out data stored in a selected one of the memory cells in the row based on voltages generated by the ferroelectric capacitor belonging to that selected memory cell and a plurality of divided ferroelectric capacitors which are distributed in the direction of the rows such that piezoelectric effects on the ferroelectric capacitors will be diminished.
