壞塊管理(Bad Block Management)

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.

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 ...

ADATA has dedicated testing equipment, software and hardware to identify bad blocks in NAND flashes, and special marks are used for bad blocks.

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。

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 ...

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。

Bad Block Management is a mechanism for handling potential faulty blocks in the manufacturing and use of NAND Flash memory. dsc09461--incoder.jpeg__PID ...

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

故障區塊管理，是由控制IC來達成故障區塊的管理機制，以偵測並標示NAND Flash中的故障區塊，提升資料存取的可靠度。控制IC的故障區塊管理機制，會在首次啟動NAND Flash時，建立 ...
