JMF608

Overviews

JMF608 is a single chip SATA III NAND flash controller. It supports up to 4 channels with 4

CE/channel NAND flash memory. JMF608 provides on-chip RAM buffer, optimized for capacity below

128GB, and is suitable to cost effective, small capacity SSD or hard drive cache application. The

embedded hardwired logic provides the

maximum 300Mbps data read and 200Mbps data write

speed to NAND flash memory.

JMF608 has the best supporting to the latest NAND flash memory, including Toshiba

19nm and Micron 20nm Flash. It also provides the hardwired Error Correction Code (ECC)

engine (up to 40b/1KB), wear leveling, and bad block management technology in this chip.

JMF608 provides embedded processor, internal masked ROM, data SRAM, SATA

link/transport layer, SATA PHY. It supports online firmware upgrade through SATA port. Data

swap between different interfaces can be done very efficiency by DMA without CPU

intervention.
