2013年11月19日 — Initial bad blocks are allowed in NAND flash, so bad block management is necessary to avoid data storage in a bad block. Bad blocks create ...

When a NAND Flash device is first used, a Bad Block Table is created, with a built-in management program in the controller checking every block. For Early Bad ...

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 ...

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.

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 ...

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.

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。

由晶圓經過檢測、切割、封裝等眾多流程才會封裝成NAND Flash顆粒(NAND Flash晶片)；在這過程中，NAND Flash顆粒裡面可能會產生壞塊，這類壞塊由於技術因素無可避免。 後期 ...

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。
