Fixed write-protect seamless memory card
First Claim
1. A memory card comprising:
- a bottom plastic piece having a plurality of lateral sides, said bottom plastic piece further having a cavity interposed along said plurality of lateral sides; and
a printed circuit board (PCB) assembly, including memory, and positioned in said cavity;
a notch formed on one of said plurality of lateral sides of said bottom plastic piece, the notch having a length that is smaller than the length of each of the plurality of lateral sides; and
a read-write plug insertably positioned into said notch where the memory card is configured to function in a read-write mode when the read-write plug is positioned into the notch and in a write-protect mode when the notch is exposed.

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.

16. A memory card comprising:
-
means having interposed therein a cavity, and having a plurality of lateral sides for housing a printed circuit board (PCB) assembly; means for storing information, positioned within said cavity; notch means formed, in its entirety, in one of the plurality of lateral sides for indicating to a host device that the memory card is in write-protect mode, said notch having a length that is smaller than the length of each of the plurality of lateral sides; and plug means that is removably positioned into said notch for causing the memory card to be read-write mode. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)

33. A method of manufacturing a memory card comprising:
-
forming a bottom plastic piece having a plurality of lateral sides to form a cavity interposed among said lateral sides, and one of said lateral sides having a notch with an exposed clamp-bar therein; positioning a printed circuit board (PCB) assembly, including memory, in said cavity; filling the cavity of the bottom plastic piece with molten plastic so that a top plastic piece is formed; and placing a clamp-device onto clamp-bar within said notch. - View Dependent Claims (34, 35)
