Samsung has announced that it has developed the world’s first toggle Double Data Rate 2.0 64-gigabit MLC NAND flash memory chips. Samsung has been able to achieve the higher density by fabricating the new chips on a 20nm process. They have a 400 megabits bandwidth are said to 10 times faster than the Single Data Rate NAND flash memory used in most smartphones and tablets in use today.
Samsung expects the chips to be integrated into the next generation of tablets and smartphones, which rely heavily on flash memory for their storage. IHS iSuppli predicts that by 2012, NAND flash memory modules with 64Gb or higher densities will account for 70 percent of NAND shipments.
