Get ready for it speed freaks, Samsung's toggle Double Data Rate 2.0 MLC NAND chips are now in production -- an industry first. The 64 gigabit flash chips manufactured using 20nm processes boast an impressive 400Mbps transfer rate. That makes these toggle DDR 2.0 chips about three times faster than toggle DDR 1.0 (a 133Mbps interface) or ten times faster than the 40Mbps SDR NAND flash in widespread use today. Look for 'em in future teardowns of tablets, SSDs, and smartphones.
