摘要： A flash-memory drive replaces a hard-disk drive using an integrated device electronics (IDE) interface. The flash drive has a printed-circuit board assembly (PCBA) with a circuit board with flash-memory chips and a controller chip. The controller chip includes an input/output interface circuit to an external computer over the IDE interface, and a processing unit to read blocks of data from the flash-memory chips. The PCBA is encased inside an upper case and a lower case, with an IDE connector that fits through and opening between the cases. The cases can be assembled with the PCBA by a snap-together, ultrasonic-press, screw-fastener, or thermal-bond adhesive method. Center lines formed on the inside of the cases fit between rows of flash-memory chips to improve case rigidity. The connector has two rows of pins that straddle the center line of the circuit board for a balanced design.

摘要： Briefly, an embodiment of the present invention includes a portable flash memory drive with a simplified mechanism, based upon the resilient properties of the material used to create the parts, for reliable extension and retraction of the device's interface plug. The portable flash memory drive is comprised of a metal housing (or case), a printed circuit board (PCB) assembly, PCB support, PCB assembly end cap, an upper, and lower housing, and in some embodiments a fingerprint sensor and/or key ring assembly. The press/push switch mechanism is located on either the side of the portable flash memory device, or the top; and relies upon the resilient properties of the material used to create the metal housing or end cap, to create a smooth, locking mechanism for the extension or retraction of the interface (i.e., USB or firewire) plug. The switching/locking mechanism relies upon grooves or notches within the material of the upper and/or lower housing for tracking and locking, coupled with protrusion tabs on the sliding components of the end cap or metal housing. Alternatively, in some embodiments of the present invention, a fingerprint sensor is also extended or retracted contemporaneously with the interface plug, and allows the end user to secure and unlock the data contained, in whole or in part, therein.

摘要： A dual-voltage secure digital (SD) card can be inserted into a legacy host or a newer host. Legacy hosts drive a high voltage such as 3.3 volts onto the power line of the SD bus, while newer hosts drive the power line with a reduced voltage such as 1.8 volts. A flash and voltage controller chip on the SD card has a controller core that operates at the reduced voltage. A voltage regulator on the SD card, or a power management unit inside the controller chip generates an internal power voltage of 1.8 volts from the dual-voltage SD bus power line. The internal power voltage is applied to the controller core and to a voltage converter that generates a flash power voltage from the internal power voltage. The flash power voltage is applied to flash-memory chips on the SD card that operate at the higher voltage.

摘要： A method for fabricating MicroSD devices includes forming a PCB panel having multiple PCBs arranged in parallel rows, with each PCB connected to its neighboring PCBs in each row by relatively narrow connecting bridge pieces, and separated from PCBs of adjacent rows by elongated stamped out blank slots. Passive components are attached by conventional surface mount technology (SMT) techniques. IC chips, including a MicroSD controller chip and a flash memory chip, are attached to the PCB by wire bonding or other chip-on-board (COB) technique. A molded housing is then formed over the IC chips and passive components using a mold that prevents formation of plastic on the upper surface of each PCB. The connecting bridge pieces are then cut using a used to connect each PCB to a PCB panel are then cut using a rotary saw. A front edge chamfer process is then performed.

摘要： A flash microcontroller has a Static Random-Access-Memory (SRAM) buffer that stores several blocks of boot code read from a flash memory. The SRAM buffer also operates as a cache of flash data after booting is complete. Cache read and write hits use the SRAM cache rather than flash memory, while old cache lines and read misses access the flash memory. Both the external host and the microcontroller are booted from boot code buffered in the SRAM buffer. A boot-loader state machine reads the flash ID and programs flash parameter registers with timing parameters for the flash memory. The flash microcontroller uses a differential interface to the external host, with a differential transceiver and a differential serial interface. Frame, packet, and encoded clock processing is also performed by the serial interface.

摘要： An ExpressCard having USB connection has a card case having two opposite first and second end portions and two opposite lateral portions. A card connector is formed at the first end portion of the card case and having a USB interface. Flash chips are implemented in the card case. A USB flash controller implemented in the card case and connected between the USB interface and the flash chips in order to provide a data access to the flash chips through the USB interface. A USB socket, in form factors of Mini-USB or Extended Mini-connector-type, is implemented in the card case and connected to the USB flash controller in order to provide a data access to the one or more flash chips therethrough. An extended Universal-Serial Bus (EUSB) host enters a suspend mode rather than poll an ExpressCard that is busy performing a memory or other operation, thereby saving power.
