badblockmanagement

故障區塊管理(Bad Block Management)可偵測及標記出快閃記憶體中的壞塊，並事先預留備用區塊。

隨著使用固態硬碟的時間越長，固態硬碟裡一些原本好的Block也會因為在使用過程中磨損，或發生一些如異常斷電等意外狀況，而變成壞塊。

This document explains how to recognize factory-generated bad blocks to manage bad blocks that develop during the lifetime of NAND Flash memory. It covers all ...

Bad Block Management detects and marks bad blocks, utilizes the reserved extra capacity to substitute the unusable blocks, and prevents data from being written ...

在NAND Flash的製造過程中所產生故障區塊，稱為Early Bad Block。在使用的過程中，也會隨著寫入、抹除的操作次數增加，而逐漸產生故障區塊，稱為Latter Bad Block。

Bad blocks are common in two classes of storage devices: (1) raw NAND (or NAND); and (2) managed flash. Managed flash devices include e-MMC and UFS and combine ...

在NAND Flash的制造过程中所产生故障区块，称为Early Bad Block。在使用的过程中，也会随着写入、抹除的操作次数增加，而逐渐产生故障区块，称为Latter Bad Block。

2021年7月17日 — The presence of factory bad blocks in NAND flash is as much based on technology as is the occurrence of further bad blocks during the lifetime.

2008年10月9日 — 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 ...

Nand flash will have some invalid blocks which is what we called bad blocks. This invalid bad block can't be used to store data because it's not stable.
