The newest offering in Micron Technology's embedded product line is its Managed NAND flash unit for feature-rich mobile handsets and other portable devices. Combining the company's NAND flash memory with a high-speed multimedia card (MMC) controller in a package is said to streamline a manufacturer's mobile design process and simplify NAND flash procurement logistics.

MMC is a high-speed, industry standard interface which provides OEMs with a technology independent, vendor independent mass storage solution. The system processor accesses the managed NAND device using a high-level, block abstracted protocol. The flash controller embedded within the low-profile BGA package handles error correction code (ECC), block erase and defect management functions.

As mass storage requirements grow, managed NAND flash will be increasingly used in mobile phones or in other portable devices. The Managed NAND devices will be available in 1Gbyte and higher densities. The new devices accommodate data transfer rates of up to 52MBps and offers manufacturers design options of 1.8V VCC (1.8V IO) or 3.3V VCC (3.3V IO / 1.8V IO) and single-level cell (SLC) or multi-level cell (MLC) technology.

NAND flash memory products are revolutionizing how people use mobile phones and other personal applications, enabling them to store large amounts of music, high-resolution images, videos, and e-mails, according to Achim Hill, senior director of strategic marketing and product development.

"We are enabling manufacturers to simplify their memory sub-system design with a more flexible, industry standard architecture that allows for the integration of high capacity, low cost NAND Flash," he said, referring to the new combined flash/multimedia card controller.

Micron is currently sampling these devices to select customers, with general sampling and production expected in 2007.
