ABSTRACT:
In an embodiment of the present invention, a memory card includes a bottom plastic piece having a plurality of lateral sides, one of which includes a notch, and a cavity interposed along the lateral sides. A printed circuit board (PCB) assembly, including memory, is positioned in the cavity. A fin-structure is created as part of the manufacturing process of the bottom plastic piece of the card. The memory card is configured to function in a read-write mode when the fin-structure is present, and in a write-protect mode when the fins are snapped off, and the notch is exposed. Alternatively, a plug device can be insertably positioned into the notch, causing the memory card to function in a read-write mode when the plug device is positioned into the notch, and in a write-protect mode when the plug device is removed and the notch is exposed.
