Creating and using a bad block table will simplify the task of managing bad blocks and prevent the accidental destruction of bad block markers.

Bad block management is designed in NAND flash memory to manage and replace cell blocks that fail over time. This brief highlights the capabilities of bad block ...

When users write data to flash, bad blocks are skipped based on the bad block table created and data is written into the next block. Reserved Block Area Method.

故障區塊管理(Bad Block Management；BBM)即控制IC的故障區塊管理機制，是用來偵測並標示NAND Flash中的故障區塊，避免日後資料存入故障區塊中，以提升資料存取可靠度。
