Samsung's 2Gb Flash Memory Powered with 60-nanomenter Process

Samsung says it has developed a faster and higher capacity version of the fastest memory chip called OneNAND while applying 60nm technology to the chip's production process for larger manufacturing efficiency. The new 2Gb OneNAND chip doubles the capacity of a OneNAND memory device - from 1Gb - and increases the chip's 'write' speed from 9.3MByte to 17MByte per second. OneNAND features NOR flash memory's fast 'read' speed and NAND flash's high-capacity plus fast 'write' speed and holds enormous market potential in a wide range of applications from multimedia phones to digital cameras, removable memory cards, PCs etc.

The chips can also be interleaved to attain an even higher capacity, while allowing each chip to independently interact with the system. The more chips that are interconnected the more data that can be processed. Example: the OneNAND chip's write capacity can be increased up to 136MByte per second when eight of the 2Gb memory chips are combined. OneNAND memory can be used as buffer memory not only for 'writes' in the system, by using faster-than-NAND 'write' speeds, but also as a buffer for high-performing 'read' operations.

OneNAND can also serve as a catalyst in the development of new product markets. A much-discussed example of this application-creating role is in how OneNAND memory is now being specified as the buffer memory inside a hybrid hard disk.
