Abstract
In certain aspects, a memory device includes a semiconductor layer, a peripheral circuit including a peripheral transistor in contact with the semiconductor layer, an array of memory cells disposed beside the semiconductor layer and the peripheral circuit, and bit lines coupled to the memory cells. Each of the memory cells includes a vertical transistor extending in a first direction, and a storage unit coupled to the vertical transistor. Each of the bit lines extends in a second direction perpendicular to the first direction. A respective one of the bit lines and a respective storage unit are coupled to opposite ends of each one of the memory cells in the first direction.
