FerriSSD® Single-Chip SSD The FerriSSD® is designed optimally for a wide range of embedded applications requiring faster access speed, small flexible form factor and reliable 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 FerriSSD® family consists of the SATA and legacy PATA series featuring 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 FerriSSD ® series support 3D SLCmode, MLCmode, and TLCmode NAND flash options. Key Features End to End Data Path Protection SMI’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 for 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 redun- dant backup) to reduce potential dPPM at customer site while extending the service life of SSD.
