Abstract
In certain aspects, a memory device includes a vertical transistor, a storage unit, a bit line, and a body line. The vertical transistor includes a semiconductor body extending in a first direction. The semiconductor body includes a doped source, a doped drain, and a channel portion. The storage unit is coupled to a first terminal. The first terminal is one of the source and the drain. The bit line extends in a second direction perpendicular to the first direction and coupled to a second terminal. The second terminal is another one of the source and the drain. The body line is coupled to the channel portion of the semiconductor body.
