摘要:
A flash-memory device has a printed-circuit board assembly (PCBA) with a PCB with a flash-memory chip and a controller chip. The controller chip includes an input/output interface circuit to an external computer over a Secure-Digital (SD) interface, and a processing unit to read blocks of data from the flash-memory chip. The PCBA is encased inside an upper case and a lower case, with SD contact pads on the PCB that fit through contact openings in the upper case. Supporting end ribs under each of the SD contact pads and middle ribs support the PCB at a slanted angle to the centerline of the device. The PCB slants upward at the far end to allow more thickness for the chips mounted to the bottom surface of the PCB, and slants downward at the insertion end to position the SD contact pads near the centerline.

Dividers between openings in the upper case that expose the SD contact pads also support the PCB at a slanted angle to the centerline of the device. The PCB slants upward at the far end to allow more thickness for the chips mounted to the bottom surface of the PCB. A user-slidable switch may be slanted to compensate for the PCB slant. The PCB may have a flex section to facilitate the slant without a slanted switch.

A Solid State Drive (SSD) device includes a printed circuit board assembly (PCBA) defining rivet holes, and a support structure including parallel side frame rails defining rivet openings and support platforms for receiving and supporting the PCBA. Compression-mated rivet sets are used to connect the PCBA to the support structure, each rivet set including a female rivet portion and an associated male rivet portion. The PCBA is mounted onto the support structure such that the rivet holes are aligned with the rivet openings of the plurality of rivet openings, and then the rivet sets are mounted and secured using an automatic rivet tool such that each rivet set extends through an associated rivet hole/opening and fixedly engaged such that the PCBA and the support structure are held between end caps of the respective male and female rivet portions.

In an electronic data storage device accessed by a host computer motherboard, a fingerprint sensor scans a fingerprint of a user of the electronic data storage device and generates fingerprint scan data. A processing unit activates an input/output interface circuit to store a data file and fingerprint reference data obtained by scanning a fingerprint of a person authorized to access the data file in a memory device having non-volatile memory, where the processing unit transmits the data file to the host computer motherboard upon verifying that the user of the electronic data storage device is authorized to access the data file stored in the memory device as a result of comparison between the fingerprint scan data from the fingerprint sensor and the fingerprint reference data. Other methods and apparatuses are also described.

A Bose, Ray-Chaudhuri, Hocquenghem (BCH) decoder is employed in non-volatile memory applications for determining the number of errors and locating the errors in a page of information. The decoder includes a syndrome calculator responsive to a sector of information. The sector includes data and overhead, with the data being organized into data sections and the overhead being organized into overhead sections. The syndrome calculator generates a syndrome for each of the data sections. A root finder is coupled to receive the calculated syndrome and to generate at least two roots. A polynomial calculator responds to the two roots and generates at least two error addresses, each identifying a location in the data wherein the error lies.
