An embodiment of the present invention includes an electronic data flash memory card (memory card) comprising a top cover (TC), a printed circuit board assembly (PCBA) and a bottom cover (BC). The TC includes a plurality of ultrasonic bonders, a plurality of breakaway tabs (tabs) and a connection device. The PCBA includes at least one memory integrated circuit (IC) and at least one controller IC. The BC includes a plurality of tabs. The TC and BC are ultrasonically bonded together, at least partially encasing the PCBA. The controller IC enables the memory card to communicate with an external host device (host) through the connection device to retrieve data files (files) from and transfer files to the host, and to store files on and retrieve files from the memory IC. The tabs are removable by the user by exerting pressure. Removal of the tabs locks or unlocks the memory card.
