The 70nm process is one step ahead of the existing 90nm process, leading to smaller, faster and less expensive memory chips. Samsung’s 70nm 4GB NAND flash writes data at the speed of 16 MB per second, a 50% improvement over the 90nm 2GB NAND flash.

8GB NAND flash memory is also going be released this summer from both Samsung and Toshiba, but Samsung still leads in process technology. Toshiba stated it will begin producing 8Gb NAND flash memory this summer, their 4Gb NAND flash memory was released earlier last year.
