FlashFX® Tera is a flash memory manager, or Flash Translation layer (FTL), that frees developers from the volatility and constraints of a single-source flash memory driver while handling wear leveling, bad block management, and other vulnerabilities of NAND flash memory. Versatility allows fast integration with over 300 flash chip part numbers. Dynamic chip select provides run-time flexibility of using just one driver image, saving money and lowering supply-line risks during production. Pre-written support includes SLC and MLC NAND and NOR parts from top manufacturers (Intel, Micron, Samsung, Toshiba and Spansion), and application processor flash controllers (like Freescale iMX 5x, i.MX 6x and Texas Instruments OMAP). Our high performance, multi-threaded flash drivers provide superior wear-leveling, bad block management, garbage collection and fast read/write speeds.

How FlashFX Tera Works

FlashFX Tera provides all the benefits of FlashFX Pro. In addition, FlashFX Tera enables OEMs to use raw MLC/SLC NAND flash memory in their products. Manufacturers of products such as MP3 players, smartphones, and personal navigators can choose from a broad range of raw MLC/SLC NAND flash parts as an alternative to the more expensive managed NAND, potentially lowering the cost of and enabling faster performance for these devices.
