Abstract:
Some embodiments include apparatuses and methods of forming the apparatuses. One of the apparatuses includes a memory cell and first, second, and third data lines located over a substrate. The memory cell includes a first transistor and a second transistor. The first transistor includes a charge storage structure located on a first level of the apparatus, and a first channel region electrically separated from the charge storage structure. The second transistor includes a second channel region located on a second level of the apparatus and electrically coupled to the charge storage structure. The first and second data lines are located on a third level of the apparatus and electrically coupled to the first channel region. The first level is between the substrate and the third level. The third data line is electrically coupled to the second channel region and electrically separated from the first channel region.
