PROBLEM TO BE SOLVED: To provide a NAND flash memory having internal error-correcting code (ECC) processing and an operation method thereof.SOLUTION: A continuous read operation may be achieved by using a data buffer having a partitioned data register and a partitioned cache register, user configurable internal ECC associated with the cache register, and fast bad block management. During a data read operation, the ECC status may be indicated by ECC status bits. When the output of a page is finished, the ECC status of all pages is determined, and stored in a status register. Before outputting corresponding page division, the ECC status of each page division is determined and output.SELECTED DRAWING: Figure 1 |
