Samsung announces 20nm NAND Flash for mobile devices

New Flash chips will be 10x faster than current NAND chips in use today

The South Korean electronics conglomerate will soon be ready to manufacture the next generation of NAND Flash chips for use in future tablets and mobile devices.

The new chips are expected to be fabricated on a 20nm scale, which will directly allow for higher densities and higher gigabytes while lowering power consumption. Other than the smaller scale, the memory chips will feature DDR 2.0 multi-level cell support for a theoretical maximum bandwidth of 400 Mbps. In fact, Samsung claims that its new Flash chips can achieve transfer speeds of up to 10 times faster than existing general-purpose SDR NAND memory chips, and three times faster than Samsung’s own 133 Mbps DDR 1.0 Flash chips.

Samsung is currently one of the key suppliers of NAND Flash for other major electronics manufacturers, including Sony and Apple, and increasingly for other mobile manufacturers as well.  Hopefully the market price of NAND chips will continue to fall since SSDs are quite notorious for their moderate to high prices.
