TECHNOLOGY - Bad Block Management

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。

During the manufacturing and usage processes, the computer creates a table of faulty blocks, recording and addressing potential issues. If a bad block ...

The blocks in which the tables are stored are procteted against accidental access by marking them bad in the memory bad block table. The bad block table ...

從Block 0 (塊0)開始確認是否有bad block mark 壞塊標誌，如果搜尋的位址是bad block就建系統bad block 表格，依序確認到最後一個block 。 Nand Flash ...

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.

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 Table Store in one good block of the last 4 blocks. There is one main table and one mirror table. For bad block mark: Update BBT on nand flash.

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 ...

控制IC的故障區塊管理機制，會在首次啟動NAND Flash時，建立故障區塊表(Bad Block Table)，也會將使用的過程中所發現的抹寫錯誤記錄在故障區塊表，並將資料移植到新的 ...

故障區塊管理(Bad Block Management)可偵測及標記出快閃記憶體中故障區塊，並事先預留備用區塊，以便在區塊故障時加以替補，如此可防止資料再度被寫入故障區塊中，進而提高產品 ...
