Product Features
Data Care Management
Various effects like data retention, read disturb limits, or temperature can impact data reliability. The latest generation of Swissbit products use special methods to maintain and refresh the data for higher data integrity.
Life time monitoring (LTM)
The Swissbit Life Time Monitoring feature enables users to access the memory device’s detailed Life Time Status and allows prediction of imminent failure, avoiding unexpected data loss. This feature uses an extended S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) interface or vendor-specific commands to retrieve the Flash product information.
Longevity
The longevity product lines use special components with a long-term supply commitment of up to 10 years. These products offer lowest TCO in demanding applications with high requalification cost.
Power fail protection
Intelligent Power Fail Protection and Recovery protects data from unexpected power loss. During an unintentional shutdown, firmware routines and an intelligent hardware architecture ensure that all system and user data will be stored to the NAND.
WAF reduction
The WAF (write amplification factor) for MLC-based products is reduced by combining a paged based FW block management with a powerful card architecture and configuration settings.
Wear leveling
Sophisticated Wear Leveling and Bad Block Management ensure that Flash cells are sparingly and equally used in order to prolong life time of the device.
Wide temperature support
Swissbit‘s embedded memory and storage solutions are designed and approved for reliable operation over a wide temperature range. The products are verified at temperature corners and prestressed with a burn-in operating functional test (Test During Burn In – TDBI).
