A semiconductor device includes first and second well regions having a first conductivity type, and a third well region between the first and second well regions having a second conductivity type different from the first conductivity type. A first active region is in the first well region. A second active region is in the second well region. A third active region is in the third well region. The third active region is closer to the second active region than to the first active region. A fourth active region is in the third well region. The fourth active region is closer to the first active region than to the second active region. A first conductive pattern is across the first and third active regions. A second conductive pattern is across the second and fourth active regions and parallel to the first conductive pattern.
