• Internal power supply protection circuit provides industry's highest level power interrup-tion resistance
• Compact dimension of 30 x 50 mm
• Supports latest MLC NAND and SLC NAND flash memory

Nov. 18, 2014

TDK Corporation presents the new SMG4A series of serial ATA II compatible industrial NAND flash memory modules, which enable storage capacities of up to 128 GB and measure only approx. 30 x 50 mm. The product will be available from January 2015.

TDK can meet the requirement of industrial usage by offering a collateral error prevention function, which overcomes the fact that in case of power failure the conventional MLC NAND flash memory products lose the data, which is not written on the disk.
The new SMG4A series does not only feature the power failure tolerance algorithm of TDK's own GBDriver RS4 controller IC, it also features TDK's internal power supply protection circuit that reliably prevents any power failure related collateral errors.

Further advantages provided by TDK's GBDriver RS4 include enhanced ECC and other functions significantly bolstering data reliability, such as read retry, auto recovery, data randomizer, and auto refresh. In addition, service life diagnosis software (TDK SMART) facilitates quantitative lifespan management.

Data security has also been enhanced. In addition to the standard ATA security complement and AES* 128-bit encryption, a TDK proprietary security function is also implemented. Data can be stored in the NAND type flash memory in encrypted form, to guard against the risk of data leaks and tampering, resulting in highly robust storage security.

The TDK SMG4A series of industrial mSATA form factor SSDs are SATA flash memory drives ideally suited for use as replacements for hard disk drives in industrial equipment and embedded devices. They combine high-speed performance, data reliability, storage lifespan, and data security on a high plane.
With the introduction of the new series, TDK can complement its existing SMG3B series and expands the product range of mSATA type NAND modules.

The products will be exhibited at TDK's booth at the Embedded Technology Exhibition (ET 2014), which will be held from November 19-21 in Yokohama, Japan.
