UA Series Memory Card

Panasonic's UA series SDHC memory card in 16 GB and 32 GB capacities utilize Panasonic’s 3D NAND Flash technology to ensure reliability, very low risk of BOM changes, and lower overall cost per GB compared to 2D NAND Flash technology. The 3D NAND-based TA series SDHC memory cards use Panasonic’s proprietary SD controller and firmware, increasing write efficiency and card lifetime as well as allowing lifetime simulations and card analysis. The 3D NAND-based TA Series microSD cards also feature a microSD UHS-I interface and outstanding performance with Class 10, UHS-I U3 speeds. The built-in power-fail robustness feature greatly minimizes the chance of data loss if power is cut to the SD card while writing data. A static wear-leveling algorithm ensures erase blocks within the NAND Flash have evenly distributed wear. Bad-block management efficiently handles physical erase blocks that become unusable over time (due to hitting their program threshold). The result is a higher overall card endurance. Quality is maintained with 100% product screening before shipment to achieve a low failure rate.
