Bad Block Information Introduction

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 ...

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

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.

2021年3月22日 — 所以在使用nand flash前Bad Block Management壞塊管理流程是重要的。 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 ...

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。

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 ...

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。
