“Building a 128Gb NAND flash memory chip with this level of complexity is an incredible achievement,” Mehrdad Mofidi, Memory Design vice president, said.

“This innovation allows SanDisk to continue to be a leader in helping our customers deliver smaller, more powerful products capable of doing more at lower cost.”

The company said that chip can store 128 billion individual bits of information on a single silicon die, which is only 170mm².


“SanDisk built the 128Gb NAND flash memory chip on the company’s industry-leading 19 nanometer (nm) process technology. A nanometer measures one-billionth of a meter, meaning that 19nm circuit lines are so small that about 3 000 of them could fit across the width of a human hair,” SanDisk said in a statement.

To add to the small size, the chip makes use of SanDisk’s X3 technology, meaning that it can write data at 18 Mb/second.
