Abstract:
In an embodiment, a semiconductor memory card includes a lead frame including external connection terminals, a lead portion, a chip component mounting portion and a semiconductor chip mounting portion, a chip component mounted on the chip component mounting portion, a memory chip disposed on the semiconductor chip mounting portion, and a controller chip. A rewiring layer is formed on a surface of the memory chip. The lead frame is resin-sealed. An electric circuit of the controller chip and the memory chip on the lead frame is formed by the lead portion, the rewiring layer and a metal wire connected to electrode pad of the chips, the lead portion, and the rewiring layer.
