Kingmax's microSD 4GB is produced with Kingpak's die stacking technology ¡V 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 ¡V 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.
