Abstract
In a 3-transistor random access memory for dynamic operation, the invention discloses a structure in which one of the transistors is stacked on the other transistor. A transistor for writing is disposed on a transistor for reading, and one of its terminals is used in common with the gate electrode of a transistor for judging data. The other terminal is connected to one of the terminals of the transistor for reading. A memory cell capable of extremely large scale integration can be obtained.
