Abstract
A storage device is provided, including: a substrate; word lines extending in a first direction; bit lines extending in a second direction perpendicular to the first direction; and a storage unit including a plurality of storage units, each of which is electrically connected to a word line and a bit line. Each storage unit includes: an active region extending in a third direction inclined with the first direction; a vertical stack of a first source/drain layer, a channel layer and a second source/drain layer; and gate stacks between the first source/drain layer and the second source/drain layer, and on opposite sides of the channel layer in a fourth direction orthogonal to the third direction, to sandwich the channel layer. The word line corresponding to each storage unit extends across the storage unit in the first direction to be electrically connected to the gate stacks on opposite sides.
