摘要： For recording or replaying in real-time digital high bandwidth video signals, e.g. HDTV, HD progressive or HD film capture signals, very fast memories are required. For storage of streaming HD video data NAND FLASH memory based systems could be used. Flash memory devices are physically accessed in a page oriented mode. According to the invention, the input data are written in a multiplexed fashion into a matrix of multiple flash devices. A list processing is performed that is as simple and fast as possible, and defect pages of flash blocks of single flash devices are addressed within the matrix architecture. When writing in a sequential manner, the data content for the current flash device page of all flash devices of the matrix is copied to a corresponding storage area in an additional memory buffer. After the current series of pages has been written without error into the flash devices, the corresponding storage area in an additional memory buffer is enabled for overwriting with following page data. In case an error occurred in the current page in one or more flash devices, the content of these current pages is kept in the additional memory buffer.

摘要： For recording or replaying in real-time digital HDTV signals very fast memories are required. For storage of streaming HD video data NAND flash memory based systems can be used. However, NAND flash memories have a slow write access, and they have unmasked production defects. Write or read operations can be carried out on complete physical data blocks only, and defect data blocks must not be used by the file system. Logical file system blocks are used which are larger than the physical data blocks. According to the invention the error reporting mechanism of the NAND flash memories is exploited. The video data is not only written to the non- volatile flash memories, but is also written to corresponding buffer slots (LFSB) of a volatile SRAM or DRAM memory operating in parallel. The video data are kept in the vola- tile memory until the flash memory holding the respective data has reported that its program or write operation succeeded. Once this has taken place, the data within the volatile memory can be overwritten in order to save memory capacity. If the flash memory has reported an error, the respective block (FSBD) of data is marked bad and will not be overwritten until the end of the entire recorded take has been reached. At this time, the marked video data from the volatile memory are copied to spare flash-blocks within the flash memories.
摘要翻译：对于在实时数字HDTV信号中录制或重放，需要非常快速的记忆。用于存储流式高清视频数据可以使用基于NAND闪存的系统。然而，NAND闪速存储器具有缓慢的写入访问，并且它们具有未掩盖的生产缺陷。只能在完整的物理数据块上执行写入或读取操作，文件系统不得使用缺陷数据块。使用比物理数据块大的逻辑文件系统块。根据本发明，利用NAND闪存的错误报告机制。视频数据不仅写入到非易失性闪速存储器中，而且还写入并行操作的易失性SRAM或DRAM存储器的相应缓冲器槽（LFSB）。视频数据保存在卷存储器中，直到保存相应数据的闪存已经报告其程序或写操作成功。一旦发生这种情况，可以覆盖易失性存储器中的数据，以便节省内存容量。如果闪存已经报告错误，则数据的相应块（FSBD）被标记为坏，并且在到达整个记录采集结束之前不会被覆盖。此时，来自易失性存储器的标记的视频数据被复制到闪存中的备用闪存块。

摘要： When recording uncompressed video and/or audio data using a digital video recorder, there is the need for a robust memory arrangement based on non-volatile, integrated circuits which is able to be fitted directly on the video camera without a long external cable connection and which is also able to be used for shots under difficult conditions, particularly action shots. The inventive memory arrangement involves the use of a number of non-volatile memory chips (10, 20) which are connected together with a favorable level of circuit complexity. To be able to cope with the high data rate for the incoming video and/or audio data, a plurality of parallel supply buses (15) are provided. Each supply bus (15) has an associated number of memory chips (10, 20). In this case, the memory word length of the memory chips (10, 20) is greater than the bus width of a data/address bus (15). A supply bus (15) with high-quality multiplexing has a respective associated number of demultiplexer/driver circuits (11, 21) which match the bus width of the supply bus (15) to the memory word length of the memory chips (10). There are respectively as many downstream memory chips (10, 20) per demultiplexer/driver circuit (11, 21) as prescribed by a value X, the value X being limited by the memory technology used, namely by the maximum number of circuits which can be connected, also called the "fan-out" value. The memory chips used are preferably NAND Flash EPROM memory chips.

摘要： For recording or replaying in real-time digital HDTV signals very fast memories are required. For storage of streaming HD video data NAND flash memory based systems can be used. However, NAND flash memories have a slow write access, and they have unmasked production defects. Erase operations can be carried out on complete flash-blocks only, and defect flash-blocks must not be used by the file system. The invention uses logical file system blocks which are larger than the physical data blocks: a logical file system block is defined as the combination of one flash-block from each flash memory of the memory system. In addition, to each memory a block indirection table (IRTBL) is assigned in order to mask physical defects in storage cells of said NAND flash memories, and to map logical data block address values (LADD) to non-defect physical block address values (PHADD).
