Swissbit Announces New SD and Micro SD Memory Cards Featuring pSLC Technology

Swissbit is announcing their new S-46 (SD) and S-46µ (Micro SD) memory cards for high performance and high endurance applications.  Swissbit is a leading European manufacturer of DRAM and flash memory devices.  Both of these new Swissbit memory cards utilize the latest MLC flash memory with a page-based firmware translation layer (FTL), along with a single bit per cell (SLC) storage mode.  This resultant “pSLC” technology creates high random performance and high endurance that dramatically exceed that of standard SD and Micro SD memory cards.

The new memory card comes with the latest technology that has longer erase capability and will last even more longer than before.
