e.MMC


BGAs mit Managed NAND sind der kleinste Formfaktor, mit dem sich zuverlässige und schnittstellenfreundliche Datenspeicher in ein System integrieren lassen.
Swissbit bietet hierfür die e.MMC-Versionen EM-20 nach JEDEC 5.0 Standard und die neue EM-30 gemäss 5.1 Standard.
Alle Swissbit e.MMC Produkte sind zuverlässige und haltbare Speichermedium mit einem wahrhaft industrietauglichen Betriebstemperaturbereich und einem detaillierten Lebensdauer-Monitoring.

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.

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).
