Abstract
A semiconductor device includes a printed circuit board having a first surface and a second surface on a side opposite to the first surface. First pads are on the first surface of the printed circuit board. An interface part is mounted on the printed circuit board via the first pads and is configured to transfer a signal between the interface part and a host device. Second pads are also on the first surface and insulated from the interface part. A semiconductor memory and a controller are mounted on the first surface. First solder balls electrically connect the first pads and the controller. Second solder balls electrical connect the second pads and the controller. A plurality of third pads are disposed on the second surface and electrically connected to the second pads allowing direct connections to the controller and memory via the second pads.
