Samsung Electronics has announced the availability of an 8Gbit OneNAND chip that takes advantage of advanced 30nm class process technology. Based on a single-level-cell NAND flash design, the new high-density chip 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 8Gbit chip features the reliability of a SLC design and the high performance of OneNAND, which reads data at 70Mbyte/s. These characteristics and a low-voltage design make it a suitable solution for handling the growing amount of code data used with touch screens and other high resolution smartphone features. By applying advanced 30nm-class process technology, the company is able to raise productivity by 40% over its previous 40nm-class design.
The chip's memory can be used as buffer memory not only for 'writes' in the system due to faster-than-NAND 'write' speeds, but also as a buffer for faster, high-performing 'read' operations due to its NOR flash interface.
