Intel Corp. and Micron Technology Inc. have released what they claim as the world's first 20nm 128Gb, multilevel-cell (MLC) device. They also announced mass production of their 64Gb 20nm NAND die.

Developed through Intel and Micron's joint development venture, IM Flash Technologies (IMFT), the 20nm monolithic 128Gb device is the first in the industry to enable a terabit of data storage in a fingertip-size package by using just eight die, the companies boasted. It also provides twice the storage capacity and performance of the companies' existing 20nm 64Gb NAND device. The 128Gb device meets the high-speed ONFI 3.0 specification to achieve speeds of 333MT/s, providing customers with a more cost-effective solid-state storage solution for today's slim, sleek product designs, including tablets, smartphones and high-capacity SSDs.

128Gb NAND

The monolithic 20nm 128Gb NAND die doubles the storage capacity and performance of the companies' existing 20nm 64Gb NAND device.

The companies revealed that their success with 20nm process technology is due to an innovative new cell structure that enables more aggressive cell scaling than conventional architectures. Their 20nm NAND uses a planar cell structure to overcome the inherent difficulties that accompany advanced process technology, enabling performance and reliability on par with the previous generation, they stated. The planar cell structure successfully breaks the scaling constraints of the standard NAND floating gate cell by integrating the first Hi-K/metal gate stack on NAND production.

128Gb NAND

The 128Gb part can store 1Tb of data in a fingertip-size package with just eight die, targeting portable, sleek devices.

The demand for high-capacity NAND flash devices is driven by three interconnected market trends: data storage growth, the shift to the cloud and the proliferation of portable devices. As digital content continues to grow, users expect that data to be available across a multitude of devices, all synchronized via the cloud. To effectively stream data, servers require high-performance, high-capacity storage that NAND delivers, and storage in mobile devices has consistently grown with increased access to data. HD video is one example of an application that requires high-capacity storage, since attempting to stream this type of data can create a poor user experience. These developments create great opportunities for high-performance, small-footprint storage, both in the mobile devices that consume the content and the storage servers that deliver it, explained the companies.

Intel and Micron noted that the December production ramp of their 20nm 64Gb NAND flash product will enable a rapid transition to the 128Gb device next year. Samples of the 128Gb device will be available in January, closely followed by mass production in 1H12.
