Latest Swissbit SD and Micro SD memory cards provide long data retention

Swissbit AG has launched its new S-40 and S-40u Series SD and Micro SD memory cards for TCO-optimised applications. These are the first SD and Micro SD cards to come on to the market that feature autonomous data refresh that requires no intervention by the host or application. Using intelligent algorithms, the memory cards deliver up to one hundred times longer data retention than conventional SD memory cards.

Both the S-40 (SD) and S-40u (Micro SD) are equipped with intelligent read disturb management (RDM) alongside an autonomous, performance-neutral background “auto refresh” process. This data care management has significantly improved data reliability and balances out the increasing limitations of MLC NAND flash during long operation time and extensive use in the field.

Data transfer rates reach up to 11 MB/s for write and up to 24 MB/s for read operations, putting them into SD3.0 speed class 6.

Diagnostic functions offering highly detailed status information plus standalone data maintenance guarantee data retention for many years, even in especially rough environmental conditions and in extreme temperatures. Both memory cards prevent read disturb bit errors even in intensive read applications and users benefit from short downtimes thanks to an extended operating life in the field and extraordinarily long data reliability.

The high-performance controller offers the best ECC (error correction code) on the market which employs modern firmware architecture and supports future MLC generations. The firmware can be updated as required.

Swissbit”s S-40 and S-40u series have been optimised for the most challenging applications where data is primarily called up for reading, such as automotive/navigation, infotainment and POI/POS applications. S-40 SD cards are available up to 32 GB; S-40u Micro SD cards are available from 4 GB up to 16 GB.
