摘要： 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.

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： A Universal-Serial-Bus (USB) device has a USB plug with reduced wobble. A USB metal wrap around the perimeter of the USB plug is attached to a housing by overmolding. A plug supporter is inserted into the front of the USB metal wrap, and has locking tabs that snap over the inside wall of the housing. Side tabs on the plug supporter fit into side slots on the USB metal wrap to secure the plug supporter inside the USB metal wrap. A circuit board with a USB flash controller has USB metal contacts on an extension end that is inserted through the housing and into the USB metal wrap. The extension end fits underneath top tabs on the plug supporter, preventing the extension end with the USB metal contacts from upward wobble when the USB plug is inserted into a USB socket.

摘要： A case-grounded flash-memory drive has a printed-circuit board assembly (PCBA) with flash-memory chips and a controller chip. The PCBA is encased inside an upper case and a lower case, with a Serial AT-Attachment (SATA) 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. Dual-axis case-grounding pins draw any electro-static-discharges (ESD) current off the upper case along a primary axis and onto a PCBA ground through a secondary axis washer that is screwed into the PCBA. The primary axis body of the dual-axis case-grounding pins fits around a PCBA notch while the secondary axis passes through a metalized alignment hole for grounding. When the SATA connector is inserted into a host, the host ground sinks ESD currents collected by the dual-axis case-grounding pins.

摘要： Content on a storage medium is protected from unauthorized use, such as excessive copying or expired playback. A storage medium contains encrypted content and an encrypted content key with rules such as usage and copy rules. An interface between a record/playback device and the storage medium has enhanced security by not passing unprotected encryption keys that might be intercepted by external hackers. A content key is combined with usage and copy rules and then encrypted with a unique key, and may be doubly-encrypted with a control key before transmission over the interface. The unique key is generated from a key matrix on the record/playback device using row and columns received from the storage medium. The storage medium stores a pre-loaded copy of the unique key. The control key is generated from a random number on the record/playback device and storage medium avoiding transmission over the interface.

摘要： A portable media player receives encrypted audio files and an encrypted content key from a central license server on the Internet. The media player supports digital rights management (DRM) by storing the encrypted audio file in its flash memory and disabling copying or playing of the audio file after a copy limit has been reached. The copy limit is a rule that is combined with the content key in a transfer key that can be encrypted together by the license server. The license server can detect cloning of the media player by reading a unique player ID from the player and detecting when too many accounts use the same unique player ID. The content key can be generated from polar coordinates of the unique player ID, player manufacturer, and song genre. A fingerprint sensor on the player can scan and compare the user's fingerprints to further detect cloning.
摘要翻译：便携式媒体播放器从互联网上的中央许可证服务器接收加密的音频文件和加密的内容密钥。媒体播放器通过将加密的音频文件存储在其闪存中来支持数字权限管理（DRM），并且在达到复制限制之后禁用复制或播放音频文件。复制限制是与许可证服务器可一起加密的传输密钥中的内容密钥相结合的规则。许可证服务器可以通过从播放器中读取唯一的播放器ID来检测媒体播放器的克隆，并检测何时太多的帐户使用相同的唯一播放器ID。内容密钥可以由唯一播放器ID，播放器制造商和歌曲类型的极坐标生成。播放器上的指纹传感器可以扫描并比较用户的指纹，以进一步检测克隆。

摘要： A sliding window of flash blocks is used to reduce wasted space occupied by stale data in a flash memory. The sliding window slides downward over a few flash blocks. The oldest block is examined for valid pages of data, and the valid pages are copied to the end of the sliding window so that the first block has only stale pages. The first block can then be erased and eventually re-used. A RAM usage table contains valid bits for pages in each block in the sliding window. A page's valid bit is changed from an erased, unwritten state to a valid state when data is written to the page. Later, when new host data replaces that data, the old page's valid bit is set to the stale state. A RAM stale-flags table keeps track of pages that are full of stale pages.

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.
