SATA III to Flash controller
JMF662 is a single chip, supports external SDRAM, SATA III to NAND flash interface. It is native design to provide
higher bandwidth for flash memory access.
JMF662 can support the maximum read and write speed to drive the limit of flash memory. JMF662 has the best
supporting to the latest NAND flash memory, including Toshiba 32nm/24nm HBL/ABL 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, JMF662 provides the on line firmware upgrade ability.
JMF662 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 JMF662 can provide the best performance.
