M.2 PCIE


Die PCIe-Schnittstelle mit NVMe-Protokoll ist zum neuen Standard für Verbraucher-, Unternehmens- und eingebettete Anwendungen geworden. Obwohl alle drei dieselbe SSD-Architektur verwenden, unterscheiden sich die individuellen Anforderungen erheblich. Während hohe Kapazität und Geschwindigkeit für Client- und Unternehmensanwendungen am wichtigsten sind und vom Markt adressiert werden, stellt die daraus resultierende Wärmeentwicklung eine große Herausforderung für eingebettete Anwendungen dar.

Die Notwendigkeit, den neuen Schnittstellenstandard zu übernehmen und dennoch nur geringe Kapazitäten zu benötigen, erfordert spezielle Produkte. Schutz vor Datenverlust bei Stromausfall ist eine starke Anforderung für eingebettete und Unternehmensanwendungen.

Für Industrie- und Embedded-Märkte adressiert Swissbit diese unterschiedlichen Anforderungen mit dem N-20m2 mit HMB-Unterstützung, geringem Stromverbrauch nd kleinen Formfaktoren sowie mit dem leistungsstarken N-30m2 mit Powersafe™-Hardware-Stromausfallschutz. Sie verfügen über Wärme- und Datenpflegemanagement und verschiedene Sicherheitsoptionen. Beide Serien sind auch in pSLC-Varianten mit stark erhöhter Ausdauer erhältlich. Der N-32m2 powersafe™ ist für NetCom- und Unternehmensanwendungen optimiert, die eine Beständigkeit der Enterprise-Klasse mit einem starken Swissbit-typischen Werteset erfordern.

Data care management
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)
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.

Power Fail Protection & Recovery
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.

Power fail protection PLUS

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.

Secure erase
Secure erase (Sanitize / Purge) / Fast erase

This feature uses an uninterruptable sequence of data erase commands. Even a power off can’t 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.

Shock & Vibration
Shock and vibration

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.

Temperature sensor
Temperature sensor

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

TRIM support
Trim support

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.

Write Amplification Factor
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
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
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).
