    摘要： An electronic data flash card is accessible by a host system, and includes a flash memory controller and at least one flash memory device coupled to the flash controller. The boot code and control code for the flash memory system (flash card) are stored in the flash memory device during a programming procedure. The flash controller transfers the boot code and control code to a volatile main memory (e.g., random access memory or RAM) at start up or reset making a RAM-based memory system. Boot code and control code are selectively overwritten during a code updating operation. A single flash controller thus supports multiple brands and types of flash memory to eliminate stocking issues.

    摘要： An electronic data flash card accessible by a host computer, includes a flash memory controller connected to a flash memory device, and an input-output interface circuit activated to establish a communication with the host. In an embodiment, the flash card uses a USB interface circuit for communication with the host. A flash memory controller includes an arbitrator for mapping logical addresses with physical block addresses, and for performing block management operations including: storing reassigned data to available blocks, relocating valid data in obsolete blocks to said available blocks and reassigning logical block addresses to physical block addresses of said available blocks, finding bad blocks of the flash memory device and replacing with reserve blocks, erasing obsolete blocks for recycling after relocating valid data to available blocks, and erase count wear leveling of blocks, etc. Furthermore, each flash memory device includes an internal buffer for accelerating the block management operations.

    摘要： Techniques for booting a host computer from a portable storage device with customized settings with secure measure are described herein. According to one embodiment, in response to detecting a portable storage device inserted into a first host computer, the portable storage device is authenticated using a private key stored within the portable storage device against a public key stored in a second host computer over a network. In response to a successful authentication, data representing a personal working environment associated with a user of the portable storage device is downloaded from the second host computer over the network. After reboot, the first host computer is configured using the obtained settings of the personal working environment, such that the user of the portable storage device can operate the second host computer in view of the personal working environment. Other methods and apparatuses are also described.

    摘要： A secure flash-card reader reads a user ID from a secure card and finds a matching entry with a hashed password in a user table on the reader. An encrypted key is received from a secure host that hashes and encrypts a password the user types into the host and the user's ID. A card decryption engine uses a random number to decrypt the encrypted key and recover the hashed password and user ID from the secure host, which is compared by a comparator to the hashed password and user ID from the user table. A mismatch causes an access controller to block access to encrypted data on the secure card. Flash data is transferred over a flash-serial buffer bus between flash-card controllers and a RAM buffer. An encryption engine on the flash-serial buffer bus encrypts and decrypts data and connects to a serial engine to the host.

    摘要： A flash-memory cache card caches data that a host writes to a hard disk drive. A flash-memory array has physical blocks of flash memory arranged into first and second data areas having M blocks each, and a wear-leveling-counter pool. An incoming logical sector address (LSA) from a host is mapped to one of M entries in a RAM lookup table using a hash of modulo M. The RAM entry stores a mapping to a physical block in a foreground area that is either the first or the second data area. Pages in the physical block are read for a matching LSA that indicates a cache hit. Full pages are written back to the hard disk and erased in the background while the other data area becomes the foreground area. A new physical block with a low wear-level count is selected from blocks in the new foreground area.

    摘要： A Universal-Serial-Bus (USB) device has a USB plug that is centered over a center-line of a circuit board. The circuit board with flash memory and a USB flash controller has metal pads that a USB connector is soldered to. The USB connector has a rear step that is about half the height of the USB connector plug. Contacts on the rear step are soldered to the metal pads on the circuit board so that the USB connector is centered around the edge of the circuit board. The overall height of the flash device can be reduced since the bulky USB connector is not attached off-center to the circuit board, but is attached at the half-height rear step. Both the USB connector and the circuit board share the same center line, allowing a printed-circuit board assembly (PCBA) to be symmetric around the center line.

    摘要： An interactive system and method for virtual ride-sharing with electric vehicle allows a vehicle operator to operate the electric vehicle, like an electric scooter, while simultaneously interacting with network users to share a riding experience through a social media site and the Internet directly from the electric vehicle. An in-vehicle camera captures vehicle data and posts vehicle data to a social media site. The vehicle operator performs social networking functions like: uploading content, downloading content, posting riding images, livestreaming content, and interacting with others on social media while operating electric vehicle. The electric vehicle comprises a step-through frame and is operable as a plug-in electric vehicle having electricity stored on board in a rechargeable battery to drive an electric motor. The vehicle has a slim aesthetic design, an aerodynamic manual brake fin, a mobile communication device holder, and an accelerator handle and a brake handle differentiated by color.
