1. A card type memory unit comprising:

  • a semiconductor package including a semiconductor chip having a nonvolatile memory with external connection terminals formed there;

    a metal frame comprising bed sections with the semiconductor chip mounted thereon and external terminal electrode sections with a step section defined between the bed section and the external terminal electrode section, the external connection terminal of the semiconductor chip being electrically connected to the corresponding bed section, and a resin section with which at least one surface of the semiconductor chip and outer peripheral surface and at least electrode surfaces of the external terminal electrode section of the metal frame are sealed such that at least the electrode surfaces of the external terminal electrode sections of the metal frame are exposed substantially flush with an outer surface of the resin section; and

    a card-type base board having a recess in which the semiconductor package is buried such that the exposed electrode surfaces of the metal frame and resin-sealed surface of the semiconductor package are exposed substantially flush with an outer surface of the base board.
