SEMICONDUCTOR MEMORY DEVICE AND SEMICONDUCTOR MEMORY CARD USING THE SAME

摘要

A semiconductor memory device is provided with a wiring board which includes an element mounting portion and connection pads. Plural semiconductor memory elements are stacked on the element mounting portion of the wiring board. The semiconductor memory element of a lower side has a thickness greater than that of the semiconductor memory element of an upper side. The semiconductor memory elements are electrically connected to the connection pads of the wiring board via metal wires.
