8th Generation NANDXtend® ECC Technology supporting current and future 3D TLC and QLC NAND

More Reliable, Efficient and Power-saving ECC technology with Innovative 4K+LDPC engine for the latest and next-generation 3D TLC and QLC NAND
NANDXtend® is an advanced firmware technology exclusively developed by Silicon Motion to meet the design requirements of SSDs with 3D NAND. Combined with LDPC (low-density parity-check), RAID Data Recovery correction technologies, the NANDXtend® three-level error correction algorithm can decode in parallel and correct errors with precision and at high speed. Together, these technologies extend the P/E cycle performance of 3D NAND, prolonging the SSD's lifespan and ensuring data integrity.

The new generation NANDXtend® includes a performance-optimized 4KB LDPC engine with an advanced firmware algorithm that delivers higher power efficiency, decoding efficiency, and correction capability to maintain consistent data throughout and provide a better user experience, even as error bits increase throughout the product lifecycle of NAND flash. 

End to End Data Path Protection

Silicon Motion's SSD controller solutions incorporate full data error detection with recovery engines to provide enhanced data integrity throughout the entire Host-to-NAND-to-Host data path. The data recovery algorithm can effectively detect any error in the SSD data path, including hardware (i.e. ASIC) errors, firmware errors, and memory errors arising in SRAM, DRAM, or NAND.
