product brief

Overview
     JMF605 is a single chip, supports SATA II to NAND flash interface. It is native design to provide higher bandwidth for flash memory access.
    JMF605 can support the maximum read and write speed to drive the limit of flash memory. JMF605 has the best supporting to the latest NAND flash memory, including Samsung, Toshiba, Hynix, Micron and IM Flash. It also provides the embedded hardware error correction code (ECC), wear leveling, and bad block management technology in this chip. In order to resolve compatibility issue, JMF605 provides the on line firmware upgrade ability.
    JMF605 provides embedded processor, internal masked ROM, data SRAM, SATA link/transport layer, SATA PHY. Data swap between different interfaces can be done very efficiency by DMA without CPU involvement. Based on the efficient architecture, the JMF605 can provide the best performance.
