Storage Technology

Various effects like data retention, read disturb limits, or temperature can affect data reliability. The latest generation of Swissbit products use special methods to maintain and refresh the data for higher data integrity.

Intelligent Firmware Power Fail Protection & Recovery protects data from unexpected power loss. After an unintentional shutdown, firmware journaling ensures that all stored system and user data will be recovered correctly and no data is lost.

In many industrial applications, the data is written to the NAND Flash once and is only read afterwards. For such cases, the firmware can be optimized in order to guarantee highest possible data retention and less read disturb.

This feature uses an uninterruptable sequence of data erase commands. Even a power off cannot stop the process, which will continue upon restoration of power. The optional enhanced feature allows the customer to sanitize the data according to different standards like DoD, NSA, IREC, etc. The purge algorithm can be started by a software command or through a hardware pin.

The sensor allows the host hardware or software to monitor the memory device temperature to improve data reliability in the target application environment.

The TRIM command allows the operating system to inform the SSD, which blocks of data are no longer considered in use and can be wiped out internally, which increases system performance in following write accesses. With TRIM Support data scrap can be deleted in advance, which otherwise would slow down future write operations to the involved blocks.

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.

Sophisticated Wear Leveling & Bad Block Management ensure that Flash cells are sparingly and equally used in order to prolong lifetime of the device.

E2E DP adds parity protection or error correction to the internal data path and RAM / ROM arrays of the Flash controller. This prevents unrecognized corruption of data.

RAID (Redundant Array of Inexpensive Disks) technology is used on NAND block level to repair a complete page fail. This provides additional protection against 3D NAND related fails.

Swissbit uses NAND products with highest quality grade in order to provide products with lowest DPPM rates and highest reliability

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.

Swissbit‘s embedded memory & 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).

The product designs are in line with the latest regulations for electrostatic discharge and electromagnetic interference. Swissbit strives to exceed these limits with our own in-house technology and production capabilities, for example with System-in-Package (SiP) competence.

The Swissbit Lifetime Monitoring feature enables users to access the memory device’s detailed Lifetime 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.

Robustness is one of our key specification targets. The design, assembly, and use of selected materials guarantee an extremely solid design, which has been validated by extensive testing.

Products with the Swissbit powersafe feature use reliable tantalum capacitors to store energy so that in case of a sudden power fail the charge will be used to harden the cache content into the NAND flash.

Swissbit offers a special protective coating on selected products. This coating is a thin polyurethane film, which protects against aggressive environmental conditions such as dust, moisture, or corrosive gas.
