Silicon Motion Leverages the industry leading technologies and experiences in NAND flash memory controller along with Multi-Chip Package (MCP) solution to introduce Ferri Family, including FerriSSD®, Ferri-eMMC® and Ferri-UFS™.

The FerriSSD®

The FerriSSD® is designed optimally for a wide range of embedded, enterprise and data center applications requiring faster access speed, small flexible form factor and reliable PCIe NVMe/SATA/PATA storage. By combining industry proven controller technology, NAND flash and passive components into a small single BGA package, FerriSSD simplifies design efforts, reduces time-to-market while protecting from NAND technology migration concerns.

Ferri-UFS™ is a highly integrated solution which combines a feature-wise flash controller compliant with the latest UFS2.1/3.1 standard and standard NAND flash memory. Its high-performance storage accessing, better power efficiency, and ease of system design make the Ferri-UFS™ a fabulous solution for automotive, industry, embedded and portable applications.

Ferri-eMMC® is optimally designed for a wide range of embedded applications and is fully compliant to the JEDEC standards for eMMC* 4.5/5.0/5.1 protocols. Available in 100/153-ball BGA packages, Ferri-eMMC® eases PCB design and enables low-cost manufacturing.

End to End Data Path Protection

Silicon Motion's FerriSSDs incorporate full data error detection with recovery engines to provide enhanced data integrity throughout the entire Host-to-NAND-to-Host data path. The FerriSSD® 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.

NANDXtend® ECC Engine

Conventional SSDs employ standard BCH and RS ECC (error correction coding) engines to initiate first-level correction using NAND shift-read-retries. In addition to this first-level error correction, FerriSSDs also implement a highly efficient second-level correction scheme using an LDPC (low-density parity-check) code and a Group page RAID algorithm (a highly efficient redundant backup) to reduce potential dPPM at customer site while extending the service life of SSD.

IntelligentScan and DataRefresh to Enhance Data Integrity

Silicon Motion's proprietary IntelligentScan function will activate automatically to scan recharge, repair, or retire the cell block (DataRefresh) according to the host behavior and working environment (eg. ambient temperature). As a result of the combination of IntelligentScan and DataRefresh, FerriSSD® can effectively prolong its service life much beyond typical NAND specifications.
