Autonomous driving capabilities are not expected overnight but rather as a gradual process with stages of evolution. Digitisation of the automotive cabin means a substantial opportunity for memory in the automotive space as cars continue their movement to become ‘servers on wheels’.
One such area is the In-Vehicle Infotainment (IVI) systems. Today’s design has a huge appetite for data storage capacity – and this appetite is only set to grow.
Mapping and navigation, music and entertainment, mirroring smartphone user interfaces, and other IVI applications occupy a growing memory footprint in new cars.
However, there are often many tradeoffs when selecting memory devices for automotive environments, which means finding a balance of capacity, endurance, and retention.
Silicon Motion significantly contributes to the automobile evolution with FerriSSD – utilising industry-proven controller technology in a small single BGA package while SSDLifeGuard ™ monitors SSD health status to ensure data integrity. FerriSSDs incorporate complete data error detection with recovery engines that provide enhanced data integrity throughout the 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.
Conventional SSDs employ standard BCH and RS ECC (error correction coding) engines to initiate the 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.
Ferri Family storage solutions are fundamental to the automotive market, providing a combination of long-term reliable operation, data integrity and data retention to ensure that the solid-state memory matches the quality and reliability of any other vital electronics system in a vehicle.
