摘要:
A semiconductor memory card includes a wiring board having an outer shape where a cut-out portion is provided at a first long-edge. A second surface of the wiring board includes connection pads disposed along a portion except the cut-out portion of the first long-edge. A memory device is mounted on the second surface of the wiring board. The memory device includes electrode pads arranged along a long-edge positioning in a vicinity of the first long-edge of the wiring board, and one-sidedly disposed so as to correspond to disposed positions of the connection pads. A controller device is stacked on the memory device.

摘要:
A plurality of semiconductor elements configuring a first element group are stacked in a step-like shape on a wiring board. A plurality of semiconductor elements configuring a second element group are stacked in a step-like shape on the first element group toward a direction opposite to the stepped direction of the first element group. The semiconductor elements are electrically connected to connection pads of the wiring board through metallic wires. Among the plurality of semiconductor elements configuring the second element group, the lowermost semiconductor element has a thickness larger than those of the other semiconductor elements.
