Samsung Electronics has successfully developed a faster and higher capacity version of what it claims is the world's fastest memory chip -- OneNAND -- while applying 60nm technology to the chip's production process for greater 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 9.3 to 17Mbps.
Featuring NOR Flash memory's fast read speed and NAND Flash's high-capacity plus fast write speed, OneNAND holds enormous market potential in a wide range of applications from multimedia phones to digital cameras, removable memory cards, PCs and digital TVs.
Moreover, the chips can 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. For example, the 'OneNAND chip's write capacity can be increased up to 136Mbps 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 read operations.
The chip can 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.
