SD – MicroSD Cards S-40
Memory cards with extremely long data retention
The new S40 memory card are the first cards on the market to feature autonomous data refresh that requires no intervention by the host or application. Thanks to intelligent algorithms, the memory cards deliver up to one hundred times longer data retention than conventional SD memory cards. S-40 (SD) and S-40u (Micro SD) memory cards are equipped with intelligent read disturb management (RDM) alongside an autonomous, performance-neutral background “auto refresh” process. This type of data care management significantly improves data reliability and balances out the increasing limitations of MLC NAND flash during long operation time and extensive use in the field.
