Overview

Silicon Motion’s SSD controller solutions break the boundaries of SSD performance, delivering ultra-high performance with a state-of-the-art low-power design. See SSDs Powered by Silicon Motion.

 

High speed combined with low power consumption: unleashing the performance of tomorrow’s SSDs

Silicon Motion’s SSD controller solutions are complete merchant ASIC/firmware solutions delivering high performance and low latency. 

  • Pushing seq. R/W speeds up to 3500/3000MB per second.
  • Designed with Intelligent Power Management to give ultra-low power consumption whether in sleep, idle or active mode.

Proprietary NANDXtend™ error-correcting code (ECC) technology

  • NANDXtend™ ECC technology combines LDPC hard and soft decoding with RAID protection. Together, these technologies extend the P/E cycle performance of 3D NAND, prolonging the SSD’s lifespan and ensuring data integrity.

  • The provision of a LDPC engine with an advanced firmware algorithm improves power efficiency, decoding efficiency and correction capability. This means that the SSD can maintain consistent data throughput and provide a better user experience, even while the bit error rate increases due to the ageing of the NAND Flash array. 

Comprehensive Data Path Protection

SMI’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.
