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.

Thin solid state drive (SSD) housing structures are described. According to one embodiment of the invention, a structure for housing an SSD includes a pair of brackets configured to support a PCBA of the SSD at either side of the PCBA via one or more ledges with corresponding fastener holes pre-configured thereon. The ledges are attached to inside surface of the brackets. Each of the brackets has a slab shape with a length and a height. The length is parallel to horizontal direction, while the height parallel to vertical. The ledges are located at mid-height and orientated substantially perpendicular to the brackets such that the PCBA is supported horizontally. In order to securely connect the PCBA with the brackets, a plurality of metal fasteners is used. The fasteners are placed through the fastener holes on the ledges and through corresponding alignment holes pre-configured on the PCBA.

Systems and methods of manufacturing and testing non-volatile memory (NVM) devices are described. According to one exemplary embodiment, a function test during manufacturing of the NVM modules is conducted with a system comprises a computer and a NVM tester coupling to the computer via an external bus. The NVM tester comprises a plurality of slots. Each of the slots is configured to accommodate respective one of the NVM modules to be tested. The NVM tester is configured to include an input/output interface, a microcontroller with associated RAM and ROM, a data generator, an address generator, a comparator, a comparison status storage space, a test result indicator and a NVM module detector. The data generator generates a repeatable sequence of data bits as a test vector. The known test vector is written to NVM of the NVM module under test. The known test vector is then compared with the data retrieved from the NVM module.

High integration of a non-volatile memory device (NVMD) is disclosed. According to one aspect of the present invention, a non-volatile memory device comprises an intelligent non-volatile memory (NVM) controller and an intelligent non-volatile memory module. The NVM controller includes a central processing unit (CPU) configured to handle data transfer operations to the NVM module to ensure source synchronous interface, interleaved data operations and block abstracted addressing. The intelligent NVM module includes an interface logic, a block address manager and at least one non-volatile memory array. The interface logic is configured to handle physical block management. The block address manager is configured to ensure a physical address is converted to a transformed address that is accessible to the CPU of the intelligent NVM controller. The transformed address may be an address in blocks, pages, sectors or bytes either logically or physically.

In one embodiment of the present invention a portable and retractable flash drive with optional rotary deploying and retracting and fingerprint verification capability is disclosed to include a cylinder assembly. The cylinder assembly has a connector situated on one end, and a fingerprint sensor situated the surface. The portable and retractable flash drive with optional rotary deploying and retracting and fingerprint verification capability further includes a rotary tube at least partially enclosing the cylinder assembly for deploying the connector. An end tube is rotatably attached to one of the two ends of the rotary tube, and an end cap is attached to the other of the two ends of the rotary tube. The rotary tube is rotated relative to the end tube to slide the cylinder assembly back and forth inside the rotary tube to extend and retract the connector.
