Abstract
Embodiments of a three-dimensional (3D) memory device are disclosed. The 3D memory device has an architecture with an increased number of bit lines. In an example, the 3D memory device includes a substrate, a plurality of memory strings each extending vertically above the substrate in a memory region, and a plurality of bit lines over the plurality of memory strings. At least one of the plurality of bit lines is electrically connected to a single one of the plurality of memory strings.
