Samsung makes 'fastest' memory chip in 60nm tech

Samsung Electronics Co. Ltd announced it has successfully developed a faster and higher capacity version of the OneNAND, touted to be the world's fastest memory chip, while applying 60nm technology to the chip's production process for greater manufacturing efficiency.

Samsung said the new 2Gbit OneNAND chip doubles the capacity of a OneNAND memory device (from 1Gbit) and increases the chip's 'write' speed from 9.3MByte to 17MBps.

Featuring NOR flash memory's fast 'read' speed and NAND flash's high-capacity plus fast 'write' speed, Samsung said its new memory product 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, Samsung said, 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 chip's 'write' capacity can be increased up to 136MBps when eight of the 2Gbit 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, Samsung explained.

Because of its high performance, the company said OneNAND can serve as a catalyst in the development of new product markets. Already, OneNAND is being specified as the buffer memory inside a hybrid hard disk. Samsung said it has demonstrated a commercial Hybrid-HDD prototype for the first time at the Microsoft WinHEC 2006 developer conference in the United States last month.
