Vertical access device and apparatuses having a body connection line, and related method of operating the same |
摘要 |
Methods, apparatuses, and systems for providing a body connection to a vertical access device. The vertical access device may include a digit line extending along a substrate to a digit line contact pillar, a body connection line extending along the substrate to a body connection line contact pillar, a body region disposed on the body connection line, an electrode disposed on the body region, and a word line extending to form a gate to the body region. A method for operation includes applying a first voltage to the body connection line, and applying a second voltage to the word line to cause a conductive channel to form through the body region. A memory cell array may include a plurality of vertical access devices. |
