Patent ID: 8274141

Claim:
A semiconductor memory card, comprising: a wiring board having an outer shape in rectangular state including a cut-out portion provided at a first long-edge, a first surface including an external connection terminal, and a second surface including connection pads, wherein the cut-out portion has a length parallel to the first long-edge of the wiring board and a width parallel to a first short-edge of the wiring board, the second surface of the wiring board includes a first pad area having a length corresponding to a residual portion except the cut-out portion of the first long-edge and a width corresponding to the width of the cut-out portion, and at least part of the connection pads is disposed in the first pad area along the residual portion of the first long-edge; a memory device, mounted on the second surface of the wiring board, including electrode pads one-sidedly arranged to correspond to the connection pads disposed in the first pad area, along a long-edge positioning in a vicinity of the first long-edge of the wiring board; a controller device, stacked on the memory device, including electrode pads arranged along at least one outer edge; first metal wires electrically connecting the electrode pads of the memory device and the connection pads disposed in the first pad area of the wiring board; second metal wires electrically connecting the electrode pads of the controller device and the connection pads of the wiring board; and a sealing resin layer formed on the second surface of the wiring board to seal the memory device and the controller device together with the first and the second metal wires, wherein the first pad area is provided along the residual portion except the cut-out portion of the first long-edge.
