摘要： A flash memory has multi-level cells (MLC) that can each store multiple bits per cell. Blocks of cells can be downgraded to fewer bits/cell when errors occur, or for storing critical data such as boot code. The bits from a single MLC are partitioned among multiple pages to improve error correctability using Error Correction Code (ECC). An upper reference voltage is generated by a voltage reference generator in response to calibration registers that can be programmed to alter the upper reference voltage. A series of decreasing references are generated from the upper reference voltage and are compared to a bit-line voltage. Compare results are translated by translation logic that generates read data and over- and under-programming signals. Downgraded cells use the same truth table but generate fewer read data bits. Noise margins are asymmetrically improved by using the same sub-states for reading downgraded and full-density MLC cells.

摘要： An extended Universal-Serial-Bus (USB) connector plug and socket each have a pin substrate with one surface that supports the four metal contact pins for the standard USB interface. An extension of the pin substrate carries another 8 extension metal contact pins that mate when both the connector plug and socket are extended. The extension can be an increased length of the plug's and socket's pin substrate or a reverse side of the substrate. Standard USB connectors do not make contact with the extension metal contacts that are recessed, retracted by a mechanical switch, or on the extension of the socket's pin substrate that a standard USB connector cannot reach. Standard USB sockets do not make contact with the extension metal contacts because the extended connector's extension contacts are recessed, or on the extension of the connector pin substrate that does not fit inside a standard USB socket.

摘要： According to certain embodiments of the invention, a flash memory card is manufactured using COB processes on a PCB panel with multiple micro cards PCB substrates. These micro memory cards are laid out in an array of 3×5 matrixes of micro cards PCB substrates. A method of molding over a PCBA is utilized, contrary to a conventional method of having two or more pieces of package components to tape together. This results in a simpler structure without the notch which enables easier singulation process and the package is moisture resistance. The final product is a single piece versus two or three pieces glued up pieces and would not separate from pieces. The final product has high water and moisture resistance, low cost and fast manufacturing throughput, no seam and aesthetically more appeasing, can stack more layers of flash memory die, and be maximized XY spaces to accommodate larger size flash memory die.

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.
