摘要: For recording or replaying in real-time digital HDTV signals very fast memories are required. storage of streaming HD video data NAND flash memory based systems can be used. However, have a slow write access, and they unmasked production defects. Write read operations carried out on complete physical blocks only, defect must not used by the file system. Logical system which larger than blocks. According to invention error reporting mechanism is exploited. The only written non- volatile memories, but also corresponding buffer slots (LFSB) SRAM DRAM operating parallel. kept vola- tile until holding respective has reported that its program operation succeeded. Once this taken place, within overwritten order save capacity. If an error, block (FSBD) marked bad will end entire recorded take been reached. At time, from copied spare flash-blocks memories.
