OREANDA-NEWS. July 24, 2012. Today TDK Corporation announced the development of a new series of SD/SDHC cards and microSD cards for industrial applications.

The new MMGBA Series of SD/SDHC cards and MUGBA Series of MicroSD cards offer high durability, advanced error correction and a lifetime monitoring function, making them well suited to industrial applications in which reliability and long service life are important features.

SD and microSD are memory card standards established by the SD Association, and SD and microSD card are increasingly finding uses in industrial equipment, in addition to digital consumer equipment. Products designed for such uses must meet demanding requirements not only with regard to data reliability but also in terms of durability, data security, and reliability monitoring.

TDKs expertise in developing NAND modules for products such as NAND flash memory controllers, CompactFlash (CF) cards, and solid-state drives (SSD) has enabled it to develop the advanced features in the new MMGBA/MUGBA series. The new SD and micro SD cards from TDK offer design engineers significantly improved reliability when compared to ordinary SD cards.

The TDK product uses high-speed, high-durability Single Level Cell (SLC) NAND type flash memory instead of the Multi Level Cell (MLC) type NAND flash memory commonly found in SD cards. Global static wear leveling achieves high-performance distributed writing, and storage life meets the requirements of industrial equipment characterised by high usage frequency and long service periods.

In addition, the rewrite life monitoring function that is highly valued by users of TDK's CF cards and SSDs has also been implemented in the MMGBA and MUGBA Series. Tolerance for power interruptions - which is another requirement for the industrial sector - has been strengthened, and a powerful error correction function that can be expanded to 16-bit ECC further elevates data reliability to previously unheard-of levels.

The MMGBA series and MUGBA series will be available from August.
