Abstract
The present disclosure, in some embodiments, relates to a memory device. In some embodiments, the memory device has a substrate and a lower interconnect metal line disposed over the substrate. The memory device also has a selector channel disposed over the lower interconnect metal line and a selector gate electrode wrapping around a sidewall of the selector channel and separating from the selector channel by a selector gate dielectric. The memory device also has a memory cell disposed over and electrically connected to the selector channel and an upper interconnect metal line disposed over the memory cell. By placing the selector within the back-end interconnect structure, front-end space is saved, and more integration flexibility is provided.
