This white paper discusses how the escalating demand for personal storage media in the consumer electronics space has fuelled growth in the NAND flash memory market and is now driving the development of a new generation of breakthrough technologies. As evidence, this paper introduces msystem’ x4 NAND technology, enabling a new generation of 4-bit/cell NAND flash media that, until now, was considered impossible to utilize. Rooted in current 2-bit/cell MLC NAND production processes, x4 NAND components enable optimal flash manufacturing cost savings.
