  • Publication number: 20080215800
    Abstract: Hybrid solid state drives (SSD) using a combination of single-level cell (SLC) and multi-level cell (MLC) flash memory arrays are described. According to one aspect of the present invention, a hybrid SSD is built using a combination SLC and MLC flash memory arrays. The SSD also includes a micro-controller to control and coordinate data transfer from a host computing device to either the SLC flash memory array of the MLC flash memory array. A memory selection indicator is determined by triaging data file based on one or more criteria, which include, but is not limited to, storing system files and user directories in the SLC flash memory array and storing user files in the MLC flash memory array; or storing more frequent access files in the SLC flash memory array, while less frequent accessed files in the MLC flash memory array.

  • Publication number: 20080198545
    Abstract: An open-frame flash-memory drive has a printed-circuit board assembly (PCBA) with flash-memory chips, a controller chip, and a Serial AT-Attachment (SATA) connector soldered to it. The PCBA is only partially encased by left and right frames or by a U-shaped bracket frame. The frames have PCBA supports and guide posts that fit near edges of the PCBA. The frames do not cover the top and bottom of the PCBA, allowing chips on the PCBA to be ventilated by unblocked air flow. Screws that attach the PCBA to the frame have metal collars that ground the frame to the PCBA's ground plane. The screws form a current path to draw any electro-static-discharge (ESD) current off the frame and onto a PCBA ground. When the SATA connector is inserted into a host, the host ground sinks ESD currents collected by the open frame.

  • Publication number: 20080192928
    Abstract: Portable electronic storage devices with hardware based security are described. According to one exemplary embodiment of the present invention, a portable electronic storage device (PESD) comprises a security engine integrated thereon. The security engine is configured to provide data encryption, data decryption, and encryption/decryption key (referred to as a key) generation according to a security standard (e.g., Advance Encryption Standard (AES)). AES is a symmetric encryption algorithm processing data in block of 128 bits. Under the influence of a key, a 128-bit data block is encrypted by transforming the data block in a unique way into a new data block of the same size. AES is symmetric sine the same key is used for encryption and the reverse transformation (i.e., decryption). The only secret necessary to keep for security is the key. AES may use different key-lengths (i.e., 128-bit, 192-bits and 256-bits).

  • Patent number: 7383362
    Abstract: A Multi-Media Card/Secure Digital (MMC/SD) single-chip flash device contains a MMC/SD flash microcontroller and flash mass storage blocks containing flash memory arrays that are block-addressable rather than randomly-addressable. MMC/SD transactions from a host MMC/SD bus are read by a bus transceiver on the MMC/SD flash microcontroller. Various routines that execute on a CPU in the MMC/SD flash microcontroller are activated in response to commands in the MMC/SD transactions. A flash-memory controller in the MMC/SD flash microcontroller transfers data from the bus transceiver to the flash mass storage blocks for storage. Rather than boot from an internal ROM coupled to the CPU, a boot loader is transferred by DMA from the first page of the flash mass storage block to an internal RAM. The flash memory is automatically read from the first page at power-on. The CPU then executes the boot loader from the internal RAM to load the control program.

  • Publication number: 20080071975
    Abstract: An electronic data flash card is accessible by a host computer, and includes a processing unit connected to a flash memory device that stores a data file, and an input-output interface circuit activated so as to establish a communication with the host computer. In an embodiment, the electronic data flash card uses a USB input/output interface circuit for communication with the host computer. A flash memory controller includes an index for converting logical addresses sent by the host computer into physical addresses associated with sectors of the flash memory device. The index is controlled by arbitration logic referencing to values from various look up tables and valid data stored in the flash memory device. The flash memory controller further includes a first-in-first-out unit (FIFO) for recycling obsolete sectors of the flash memory device in the background process so that they are available for reprogramming.
