Samsung, the world's largest maker of computer memory chips, unveiled a 64-gigabit NAND flash memory chip based on finer process technology using circuit elements that are 30 nanometers wide.
Samsung touted the development of the chip as a world first and said the new chip marks the eighth straight year that memory density has doubled and the seventh straight year that the nanometer scale has improved for NAND flash. The company said it plans to begin production of the chip in 2009.
Last year the company announced 32-gigabit NAND flash memory chip based on 40-nanometer process technology. Production of that chip will begin 2008. The bulk of Samsung's flash memory chips in 2007 are produced using 50-nanometer process technology.
