[PDF] Understanding Bad Block Management in NAND Flash Memory

壞塊與來源. 固態硬碟的NAND Flash顆粒是由一個個小小的Flash塊所組成，Flash塊則會有好有壞。固態硬碟的壞塊來源主要有兩方面：. 出廠壞塊（Factory Original Bad Block）.

快閃記憶體的故障區塊分為兩種類型：出廠時固有的故障區塊(Early Bad Blocks)和使用後產生的故障區塊(Later Bad Blocks)。固有故障區塊多於製程中產生，通常占總容量的1%。這 ...

Before a system uses NAND flash for storage, it is highly recommended that a bad block table be created from any initial bad block markers ...

When a bad block is detected, a reserved block may be used as a replacement and managed by a logical to physical table through the host processor or the managed ...

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有效區塊 ...

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 ...

The nand driver supports various types of bad block tables. Per device The bad block table contains all bad block information of the device which can consist ...

BBT means bad block table which will be stored onto NAND flash.Without BBT, NAND driver will scan all the blocks on NAND flash to get the bad block information ...

The bad block table consists of two subtables, a primary copy and a mirror copy. Each subtable is in a separate block, beginning in the first ... OLPC NAND Bad Block... · Bad Block Table Location · Bad Block Table Format

In the skip block method the algorithm creates the bad block table and when the target address corresponds to a bad block address, the data is stored in the ...
