Zusammenfassung:A semiconductor memory device includes a substrate; a first impurity region of a first conductive type; a second impurity region of the first conductivity type apart from the first impurity region in a first direction; a first transistor including a first electrode disposed between the first impurity region and the second impurity region; a third impurity region of the first conductive type apart from the first impurity region in a second direction that crosses the first direction; a fourth impurity region of the first conductive type apart from the third impurity region in the first direction; a second transistor including a second electrode disposed between the third impurity region and the fourth impurity region. The semiconductor memory device includes an active region of the first conductive type between the first transistor and the second transistor.
