FerriSSD IC Solution

The FerriSSD® is designed optimally for a wide range of embedded applications requiring faster access, small form factor and reliable SATA/PATA/PCI interface storage.

By combining Silicon Motion (SMI)’s proprietary industry proven controller technology, NAND flash and passive components into a single BGA package, FerriSSD® simplifies design efforts, reduces time-to-market while protecting from NAND technology migration concerns.

FerriSSD® also comes with advanced firmware features as well as the provision for customized firmware – enabling highly reliable and differentiable storage solutions.

    • Field programmable firmware available

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 redundant backup) to reduce potential dPPM at customer site while extending the service life of SSD.

IntelligentScan and DataRefresh to Enhance Data Integrity

SMI’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 effective prolong its service life much beyond typical NAND specifications.
