摘要： High endurance non-volatile memory devices (NVMD) are described. A high endurance NVMD includes an I/O interface, a NVM controller, a CPU along with a volatile memory subsystem and at least one non-volatile memory (NVM) module. The volatile memory cache subsystem is configured as a data cache subsystem. The at least one NVM module is configured as a data storage when the NVMD is adapted to a host computer system. The I/O interface is configured to receive incoming data from the host to the data cache subsystem and to send request data from the data cache subsystem to the host. The at least one NVM module may comprise at least first and second types of NVM. The first type comprises SLC flash memory while the second type MLC flash. The first type of NVM is configured as a buffer between the data cache subsystem and the second type of NVM.

摘要： A multi-partition Universal Serial Bus (USB) device has a flash memory with multiple partitions of storage. Some partitions are for different operating systems and store OS images. Another partition has a control program while a user partition stores user data and user configuration information. The control program can test the multi-partition USB device and instruct the host computer BIOS to mount a partition from its flash memory as a drive of the host computer. The host computer can then be rebooted. The OS image from the flash memory is loaded into main memory during rebooting, and the host computer executes a new operating system using the new OS image. The user can press buttons on the multi-partition USB device to select which OS to load, and to begin rebooting. Virus removal programs in the alternate OS can help recover from a virus in the primary OS.

摘要： An electronic data flash card includes a random number generator that generates a random number stored in the card and a host system each time the card is accessed by the host system. The random number is used by the host system to encrypt a logical branch address, a user password, and user data that is written to and stored in a secure area of the card. The random number is encrypted using a key associated with the card, and the encrypted random number is stored by the card with the associated encrypted data. The random number is not stored in the host system. A new random number is generated each time the card is queried. In a read process the host system decrypts the encrypted random number using the key, then uses the random number to decrypt the associated encrypted data. Access to read/write processes are password protected.

摘要： A low-profile Universal-Serial-Bus (USB) device includes a PCBA in which all passive components and unpackaged IC chips are attached to a single side of a PCB opposite to the metal contacts. The IC chips include, for example, a USB controller chip and a flash memory chip, or a single-chip (combined USB controller/flash memory) chip. Multiple flash IC chips are optionally stacked to increase storage capacity. The IC chip(s) are attached to the PCB by wire bonding or other chip-on-board (COB) technique. The passive components are attached by conventional surface mount technology (SMT) techniques. A molded housing is then formed over the IC chips and passive components such that the device has a uniform thickness. The low-profile USB device is optionally used as a modular insert that is mounted onto a metal case to provide a USB assembly having a plug shell similar to a standard USB male connector.

摘要： A high volume testing/formatting process is provided for Universal Serial Bus-based (USB-based) electronic data flash cards (USB devices) that meets the increasing demand for USB electronic data flash cards (USB devices). A test host is simultaneously coupled to the multiple USB devices (e.g., using a multi-port card reader or a probe fixture), a controller endpoint value is read from each of the USB devices and verified with a known good value, and then testing/formatting is performed on each of the USB devices by writing predetermined data into each USB device in a pipelined manner, then reading out and testing the predetermined data. In one embodiment, the test host implements a special a USB driver that blocks standard USB registration procedures upon detecting the plurality of USB devices. Control and/or boot code data are written onto the flash memory device (i.e., instead of being provided on a controller ROM).
