SEMICONDUCTOR MEMORY DEVICE HAVING STACKED CAPACITOR-TAPE MEMORY CELLS

摘要

In a semiconductor memory device having stacked capacitor-type memory cells, the capacitor of each memory cell comprises an electrode, an insulating layer, and a counter electrode. The electrode is connected electrically to a source or drain region of a transfer transistor and extends over a part of a word line adjacent to another word line serving a gate electrode of the transfer transistor, at which part no memory cell is formed.
