Micron Technology has announced support of the newly-ratified JEDEC eMMC 4.4 standard with its portfolio of managed NAND solutions for mobile applications.

Designed using Micron's 34nm NAND technology, eMMC 4.4 products now offer increased security options and NAND partition management, allowing handset manufacturers to swiftly and easily transition to the new features offered in NAND.

Micron said it is taking sample orders for delivery in July, and expects to be production-ready in fall 2009.

By combining the NAND and flash memory controller in one package, Micron's eMMC solutions simplify the application interface design and alleviate the host processor from low-level flash memory management, said the company. The eMMC 4.4 standard is backward compatible with previous MMC standards.

The NAND partitioning feature of the eMMC 4.4 standard allows designers to configure partitions of the MLC NAND to act as SLC NAND and securely store and execute handset boot code, according to Micron. Doing this in MLC NAND eliminates the need for an extra SLC chip and reduces the component count, simplifying product integration and freeing up board space.

Also new for the eMMC 4.4 standard are heightened security features that restrict access to the phone's critical software, including the boot code and operating system, Micron indicated. Specific security features include power-on write protection, permanent write protection and secure memory block.
