Abstract
A dynamic random access memory has a plurality of memory cells, each cell is defined by a substrate made of semiconductor material, a capacitor for storing data, a first transistor connected to one side of the capacitor. The first transistor is formed of a thin film transistor, and a second transistor of the memory cell is connected to the other side of the capacitor. By this arrangement, the size of each memory cell is reduced.
