FerriSSD® Quick Reference
FerriSSD® BGA Solid-State Drive
Key Features
The FerriSSD® is designed optimally for a wide range of embedded applications requiring faster access, small form factor and reliable SATA/PATA 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.
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 Probability of RBER algorithm (a highly efficient STD BCH ECC LDPC ECC redundant backup) to reduce Group Page RAID potential dPPM at customer site protect data further! while extending the service life TLC when ~Max PE of SSD. 20

Key Features
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.

FerriSSD® Modules
FerriSSD® Modules
FerriSSD® Modules are designed optimally to be easily adopted for a wide range of industrial embedded applications requiring faster access, industrial standard form factor and reliable SATA / PATA / PCIe* non-volatile memory storage. By combining industry proven controller technology with advanced firmware features, FerriSSD® Modules simplify design efforts, reduces time-to-market while protecting from NAND technology migration concerns. FerriSSD® Modules are available with MLC, SLC & SLC mode options and are offered in densities up to 256GB*. To further ensure data integrity, FerriSSD® Modules are designed with advance IntelligentScan with DataRefresh can prolong its usage life much beyond typical NAND specifications. The unique features-FastWrite, PowerShield and DataPhoenix - are designed to handle sudden power loss by working together to ensure no data is lost even in the event of a sudden power off. FerriSSD® Modules also provide for customized firmware - enabling highly reliable and differentiable storage solutions, a perfect choice for boot-SSD in server, automotive IVI, network appliances and other systems. Adopting FerriSSD® Modules will accelerate development time, enable upgradability and replaceability of storage system as well as enhance the overall performance, eliminate potential downtime, and reduce the total cost of ownership.

Server grade data protection: IntelligentScan with DataRefresh IntelligentScan with DataRefresh has proven to be extremely effective against read disturbance and data retention in high temperatures. With IntelligentScan, the FerriSSD® module’s firmware will respond to various usage conditions to intelligently determine where, when and how frequently to scan the SSD. When IntelligentScan identifies overstressed cells, SMI’s proprietary DataRefresh function will be activated automatically to recharge, repair or retire the cell block accordingly. As a result of the combination of Intelligent Scan and Data Refresh, the FerriSSD® module can prolong its usage life much beyond typical NAND specifications.
