Samsung Electronics Co., Ltd. announced today the industry's first production of a 3-bit-cell (3bit), 64 gigabit NAND flash using 20 nanometer-class process technology. The highly advanced new chip can be used in high-density flash solutions such as USB flash drives (UFDs) and Secure Digital (SD) memory cards.
"Samsung has repeatedly provided the market with leading-edge NAND flash solutions, including the introduction of 30nm-class, 32Gb 3-bit NAND flash last November," said Seijin Kim, vice president, Flash Memory Planning/Enabling, Samsung Electronics.
"By now entering into full production of 20nm-class 64Gb 3-bit devices, we expect to accelerate adoption of our high-performance NAND solutions that use Toggle DDR technology, for applications that also require high-density NAND."
Samsung's 20nm-class, 64Gb 3-bit NAND has a 60 percent higher productivity level than 30nm-class, 32Gb 3-bit NAND. The device also offers improved performance by applying Toggle DDR (Double Data Rate) 1.0 specifications, compared to those of SDR (Single Data Rate) based 30nm-class NAND chips.
