Flash memory chip Rx series

NAND

NAND-type Flash Memory has been changing its memory cell structure, cell size, and functions, and increases in its capacity and reductions to its cost have been undergoing rapid promotion through downsizing. However, if the flash memory generation change accelerates without keeping cross-generational compatibility, procurement of NAND-type Flash Memory may become difficult and a larger risk of restricting system introductions and system designs may arise. The TDK GBDriver RA6 eliminates these risks by controlling the latest flash memory (TwoPlane-write Flash Memory) while maintain ing support for existing NAND-type Flash Memory. Aside from this, the GBDriver RA6 supports UltraDMA Mode2 with a maximum transfer speed of 33.3MB/s, in order to control the latest flash memory with the industry’s highest level of speed. Moreover, the architecture of wear levelling has been renewed. Even for disproportionate writing to memory, the GBDriver RA6 controls write levelling in order to prevent writing from being concentrated on any particular part of the memory. Along with the newly equipped system-strengthening functions (the smart command support and the function of setting all sector numbers [clipping function]), this pro-longs the life of NAND-type Flash Memory and increases reliability in using NAND-type Flash Memory as an HDD substitut
