High Performance SSD Controller (4 Channels with DRAM)

product brief

     JMF667H is a single chip, supports external DDR3 DRAM, SATA III to NAND flash interface. It is native design to provide higher bandwidth for flash memory access.
    JMF667H can support the maximum read and write speed to drive the limit of flash memory. JMF667H has the best supporting to the latest NAND flash memory, including Toshiba 32nm/24nm HBL/ABL, 19nm Flash, Intel/Micron 20 nm and 25 nm. 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, JMF667H provides the on line firmware upgrade ability.
    JMF667H 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 JMF667H can provide the best performance.
