We use the JMicron JMF602 single chip contorller with Serial ATA Gen II and USB 2.0 combo to NAND flash interface. It is an innovative design to provide high bandwidth for flash memory access. JMF602 can support the maximum read and write speed to drive the limit of flash memory. It supports up to 256 NAND Flash chips. JMF602 is available in 211 pin TFBGA (12mm x 12 mm) package.

JMF602 supports a variety of popular NAND flash memory, including Toshiba, Samung, Hynix/ST and Intel/Micron Flash. With the embedded hardware error correction engines and the robust bad block management technology, JMF602 is suitable for PC and industrial solid state drive applications. In addition, dynamic and whole drive static wear leveling are used in JMF602 to provide the best extension of drive life time.
