Numonyx has announced the first samples of multi-level cell (MLC) NOR flash memory products using 45nm process technology.

Numonyx NOR flash memory chips are most commonly used in mobile phones to run critical phone operations, manage personal data and store photos, music and videos.

The 45nm 1Gb monolithic device is based on the Numonyx Strataflash memory architecture and is drop-in compatible with Numonyx high-volume 65nm NOR flash chips.

The technology will increase the speed in which data is written up to 50 per cent over the previous generation, claims Numonyx.

‘The mobile phone memory segment remains large and the need for high-density, low-cost nonvolatile NOR flash memory continues to drive aggressive scaling requirements,’ said Ed Doller, chief technology officer at Numonyx.

‘Numonyx engineers overcame major scaling limitations by developing process techniques to produce the 7th generation MLC NOR flash on 45nm technology.’ Numonyx technologists also claim to have achieved a breakthrough in how they designed this latest generation of its NOR flash memory technology.

Using a self-aligned contact (SAC) approach, the method allows Numonyx NOR flash memory products to continue to scale while maintaining backward compatibility and high levels of quality and reliability.

Numonyx is sampling in limited quantities and densities, and plans to introduce products on the new technology this year.

Full production is expected in 2010.
