The GBDriver RS1 controller secures expanded spare space for future bad blocks, has improved block control structures within the controller, and is equipped with an address control mechanism structure that can be used even when a large number of inherent bad blocks occur in the memory in a short period.
Micron's e-MMC products also greatly simplify system design by removing the requirements of the host memory controller to support NAND software drivers and complex NAND management techniques, including error correction code (ECC), wear leveling, and bad block management--replacing all of this complexity with a simple and ubiquitous MMC interface.
Flash drivers are fail-safe and include multiple volumes, wear-leveling, directories, bad block management and ECC algorithms

Based on Greenliant's internally-developed NAND controller, eMMC NANDrive has advanced wear-leveling, bad block management and error correction code (ECC) capabilities to significantly extend the life of the product.
The controller marks the debut of Cypress's fast-interleaving N-Xpress[TM] MLC NAND Flash control technology, with static wear-leveling, bad block management and 4-bit ECC (Error Correction Coding) to support up to 16 SLC/MLC NAND devices.
Based on Greenliant's internally-developed NAND controller, NANDrive has error correction code (ECC) capabilities with advanced wear-leveling algorithms and bad block management to significantly extend the life of the product.
New flash components based on ONFi's BA NAND flash specification can incorporate traditional NAND-specific functions such as error-correcting code (ECC), wear-leveling, and bad block management in the internal memory controller, freeing the host of these tasks.
NAND Flash bad block management support in ScanExpress JET.
Reliability: SanDisk patented flash management technology and extensive IP portfolio provide dynamic and static wear leveling algorithms and dynamic bad block mapping, including advanced error detection and correction code (EDC/ECC) to ensure high data reliability.
This method is not only more reliable, but also improves performance because only the bad block is reconstructed, as opposed to the entire stripe containing the bad block, as in most other RAID methods.
The new ClearNAND products perform error-correction within the NAND Package itself and allow wear-leveling, compaction, Bad Block Management and other flash management functions to be done in software.
The SSD controllers' built-in bad block management, auto-wear leveling and error correction ensure reliable high speed operation and minimize the burden on the host processor to extend the life of the Flash media.
FlashFX[TM] Tera features pre-written support for over 300 flash parts, works with virtually any NAND controller, and features wear leveling, bad block management, and background compaction for unrivaled performance.
Additional features include wear leveling, write protect and error detection and bad block correction.
