ABSTRACT:
A semiconductor memory device which includes a plurality of memory cells each having a capacitor, and peripheral circuits of the memory cells, integrated on a semiconductor substrate. Each capacitor has a storage electrode and an electrode opposite to the storage electrode, the opposite electrode being connected to a ground line, wherein, the ground line connected to the opposite electrode of each capacitor is separated from the other ground lines connected to the peripheral circuits. All of the ground lines are connected to a common portion having an impedance lower than the impedance of each ground line, whereby data stored in the capacitors is prevented from being destroyed.
