Abstract
A semiconductor dynamic random access memory device or a ferroelectric random access memory device has dummy cells arranged around memory cells of each array so as to prevent the memory cells from a pattern defect during a fabrication process, and the dummy cells have dummy capacitors connected through a power distributing line to an internal power source so as to render the internal power voltage on the power distributing line stable.
