Samsung 30nm-based OneNAND chip for smartphones unveiled
Samsung has announced new high-performance NAND Memory – a 30nm-class, 8 Gigabit OneNAND Chip for use in smartphones. Based on a single-level-cell (SLC) NAND flash design, the new high-density OneNAND addresses the need for more code data storage in smartphones, a trend being driven by the increasing use of diverse application software and larger amounts of multimedia software. The high-density OneNAND memory is now sampling with volume production scheduled by the end of this month.

OneNAND memory can be used as buffer memory not only for ‘writes’ in the system – thanks to its faster-than-NAND ‘write’ speeds, but also as a buffer for faster, high-performing ‘read’ operations thank to its NOR flash interface.

Samsung's 8Gb OneNAND features the reliability of a SLC design and the proven performance of OneNAND, which reads data at 70 megabytes per second (MB/s), more than four times the speed of conventional NAND (17MB/s). These characteristics and a low-voltage design make it a particularly attractive solution for handling the growing amount of code data used with touch screens and other high resolution smartphone features. In addition, by applying advanced 30nm-class process technology, Samsung is able to raise productivity by 40 percent over its previous 40nm-class* design.

Since 2004, Samsung has expanded the adoption of its OneNAND as a high-performance solution that can be applied to handset applications without having to develop separate software.
