SEMICONDUCTOR MEMORY DEVICE WITH DUAL STORAGE NODE AND METHODS OF MANUFACTURING AND OPERATING THE SAME

摘要

A semiconductor memory device with a dual storage node structure as well as methods of fabricating and operating such a device are provided. The semiconductor memory device includes a substrate, a first transistor formed on the substrate, a first storage node connected to a source region of the first transistor, a second storage node connected to a drain region of the first transistor, and a plate line commonly contacting the first storage node and the second storage node.
