As the storage capacity of NAND Flash memory increases rapidly with finer designs, memory cell structures and functions are undergoing extreme changes, making it increasingly difficult to maintain compatibility between generations. To address this issue, the GBDriver(R) RA6 series of controllers are fully compatible with earlier NAND Flash memory chips and can control the latest two-plane write Flash memories. GBDriver(R) RA6 controllers can control up to eight 8-Gbit NAND Flash memory chips for a maximum of 8 GByte.
The GBDriver(R) RA6 series features improved NAND Flash memory management methods, and even when data writing to the memory is excessively concentrated, data is not concentrated in one area of the memory, increasing multiple use and capacity of the memory chip and enhancing reliability even when NAND Flash memory chips are used in place of HDDs. GBDriver(R) RA6 controllers support Ultra DMA Mode 2, which achieves maximum data transmission speeds of 33.3 MByte/s, making them suitable for controlling the latest Flash memory chips with the industry's fastest data transmission speeds.
The main applications are storage applications for operating systems, file systems, and user data on consumer and industrial embedded system devices and IT equipment, and applications with Silicon Disks including hybrid PCs and PCMCIA ATA cards are also anticipated.
