Abstract
A ROM cell includes first and second three-dimensional transistors. The second transistor is formed above the first transistor, and the channel portions of the first and second transistors overlap each other. First data is stored depending on whether first and second local interconnects connected to the nodes of the first transistor are connected to a same line, or different lines, out of a bit line and a ground power supply line. Second data is stored depending on whether third and fourth local interconnects connected to the nodes of the second transistor are connected to a same line, or different lines, out of a bit line and a ground power supply line.
