Abstract
As flash memory gains its momentum in the storage market of embedded systems, existing fault detection algorithms face serious challenges due to the special characteristics of NAND flash memory and the rapid degradation of its reliability. This research proposes efficient fault detection algorithms to detect the faults of NAND flash memory in a systematic way. A sampling policy with a write parallelization strategy is also proposed to further enhance the efficiency of the fault detection algorithms. The sampling policy is later evaluated based on selected fault distribution models to show its effectiveness and efficiency on the fault detection of NAND flash memory.
