Overview

The FerriSSD® is designed optimally for a wide range of embedded 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.

The PCIe NVMe FerriSSD® family supports PCIe Gen3 x4 / x2 NVMe 1.3 designed optimally for high-performance mission-critical applications. The FerriSSD includes embedded DRAM series for Data Redundancy with PCIe Gen3 x4 interface exhibiting high performance and DRAM-less series featuring the best balance of saving/performance - cost saving from eliminating DRAM while maintaining DRAM-like performance via HMB (Host Memory Buffer). Both available in 3D TLCmode™, MLC mode™, and SLCmode™, the unique flexible design can support multiple capacity configurations enhanced by via Silicon Motion's proprietary full end-to-end data path protection technologies.

The SATA/PATA FerriSSD® family consists of the SATA and legacy PATA series featuring a high throughput transfer rate with optional embedded DRAM to enhance data storage efficiency and high random read/write IOPS. The 4th generation FerriSSD leveraging Silicon Motion's most advanced technologies, including IntelligentScan, DataRefresh, high bandwidth LDPC ECC engine with SMI group RAID, and End-to-end data path protection to provide unsurpassed data integrity in a non-volatile storage device. All SATA/PATA FerriSSD® series support 3D SLCmode™, MLCmode™, and TLCmode™ NAND flash options.

Technologies

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.
