Kingmax Digital Inc, the leading Taiwan-based manufacturer of memory storage products, is the world's first company to release a 4GB SD 2.0 compliant microSDHC memory card, which will be on display at 2007 International CES from January 8 to 11 in Las Vegas. With this product, Kingmax answers continued consumer demand for high capacity and speed in memory products.

The competitive field for memory cards has thrived with the emergence of digital cameras, and the demand for memory cards is spreading like wildfire for use in mobile phone devices. As mobile devices are moving towards a unified storage format in 2007, microSD is poised to corner the entire market, and Kingmax Digital is ready to herald a new era in memory storage with its 4GB microSDHC card.

With this new product, Kingmax has fully realized the allure of microSD, which lies in its ability to accommodate smaller form factor and portability in product design, its ease of use on various platforms, and backwards compatibility.

Made with Leading Memory Technologies -- a Powerful Combination

Kingmax Digital is the world's only company to have a vertically integrated production capacity, covering the entire industry chain from wafer procurement, to packaging and testing, to mass production. To create the 4GB microSDHC card, Kingmax has integrated the world's most advanced flash storage technology from the top four manufacturers in the field: Kingpak Technology, Samsung, Silicon Motion, and Nanya Technology.

Kingmax's microSD 4GB is produced with Kingpak's die stacking technology – the world's most advanced and which exercises precise control in grinding the thickness of each die. Kingmax also uses Kingpak's proprietary PIP packaging technology, the world's most advanced packaging technology that uses substrate from Nanya Technology, and wire bonding using 20 um gold wire.

Nanya's super-thin substrate, which measures only 0.11mm, makes the perfect choice over normal substrate, which has a thickness of 0.2mm, is difficult for use in small form factor memory card production. The thickness of each die is only 25 um, and is composed of stacks of 8 layers.

The Kingmax microSDHC also utilizes Samsung's 63 nanometer process technology – the world's smallest, which allows a similar 4Gb flash memory to have an even smaller form factor so as to accommodate future designs in creating higher capacity memory cards. This technology allows Kingmax to easily supply twice as much capacity in its memory card products as its competitors.

The microSDHC also uses Silicon Motion's SMI 268 controller, a flash memory controller made from a 0.18um process technology. The controller supports dual channel read speeds of up to 150X (22.5 MB/sec) and read speeds of up to 127X (19.1 MB/sec), and complies with flash products of different speed classes for minimum write speed (Classes 2, 4, 6). Its low power consumption makes it suitable for device batteries for aviation and marine use, and it is currently the market's best controller supporting SD 2.0 specifications. The SMI 268 allows for complete compatibility with all SDHC specification mobile phones and digital cameras.

Kingmax's 4GB microSDHC memory card is the perfect solution for digital camera and MP3 player storage needs and also a perfect choice for SDHC specification products. Kingmax SDHC memory cards support HD and DVD video, as well as Super VCD, DVR and digital TV's MPEG-4 HD image formats.

In 2007, with its world-leading technology, Kingmax Digital looks forward to International CES in Las Vegas, where the 4GB microSDHC will be sure to capture the attention of the technology world.
