DailyTech has learned that JMicron will be unveiling a new NAND flash controller for use in Solid State Drives (SSDs) in the near future. The JMF612 chip uses an ARM9 core in a 289-ball TFBGA package, and will support the use of up to 256MB of DDR or DDR2 DRAM as an external cache.
The new chip was designed to remedy stuttering problems during random write operations, which has plagued SSDs using the JMF602 flash controller. JMicron rushed out a JMF602B chip to address shortcomings, but was only partially successful. Several firms decided to combine two JMF602B chips and an internal RAID chip from JMicron to boost performance. Although it raised costs significantly, it was still cheaper than controllers from Samsung and Indilinx, which were not yet available at the time. It was for this reason that SSDs like OCZ's Apex and G.Skill's Titan series were born.
The JMF612 chip is designed especially for a new generation of NAND flash chips built using smaller process geometries that will be entering the market soon. The new flash chips will be smaller, faster, and cheaper to manufacture. IM Flash Technologies, a joint venture between Intel and Micron, is already building 34nm NAND, while 32nm NAND from Samsung and Toshiba will soon be entering production. The use of a cheap single-chip controller and new higher density flash chips could cut prices in half by the vital Christmas shopping season.
