A memory includes a U-shape layer on a substrate; a first diffusion layer provided at an upper part of the U-shaped layer; a second diffusion layer provided at a lower part of the U-shaped layer; a body formed at an intermediate portion of the U-shaped layer between the first and the second diffusion layers; a first gate dielectric film provided on an outer side surface of the U-shaped layer; a first gate electrode provided on the first gate dielectric film; a second gate dielectric film provided on an inner side surface of the U-shaped layer; a second gate electrode provided on the second gate dielectric film; a bit line contact connecting the bit line to the first diffusion layer; a source line contact connecting the source line to the second diffusion layer, wherein cells adjacent in the first direction alternately share the bit line contact and the source line contact.
