USB drives are applied to store and transfer files, photos, music, and videos. USB flash controllers should support 3D NAND flash in time. Solid State System USB 3.2 Gen 1 flash controllers deliver high data integrity, high stability, and cost - effective solution. These controllers deliver high data transfer rates with integrated 32 bit compatible microprocessor and support all kinds of DDR NAND. With advanced ECC correction ability, and abundant NAND technology knowledge, the controllers ensure the highest reliability of NAND management. USB 3.2 Gen 1 controllers are compliant with USB 3.2 Gen 1 specification, and is backward compatibility with 1.1/ 2.0.
