Abstract
A storage device includes a substrate, a storage unit array, and word lines extending in the first direction. The storage unit array includes storage units arranged along a first direction and a second direction. Each storage unit includes: an active region extending in a third direction and including a vertical stack of first source/drain, channel and second source/drain layers, and a gate stack between the first and second source/drain layers in a vertical direction and sandwiching the channel layer from at least two opposite sides. First source/drain layers of each column are continuous to form a bit line extending in the second direction in a zigzag shape. Each word line extends in the first direction to intersect the active regions of a respective row, and is electrically connected to the gate stack of each storage unit on two opposite sides of the channel layer.
