e∙MMC 4.4 – Offering the Latest Features for Managed NAND Solutions
Our managed solution, with its focus on new features like advanced partitioning and security, is one of the first implementations of the JEDEC-standard 4.4 spec. The new NAND partitioning feature enables designers to configure partitions in the MLC NAND to act as SLC NAND to safely and securely store and execute handset boot code. Doing this in MLC NAND eliminates the need for an extra SLC chip and reduces the component count—simplifying your BOM and product integration and freeing up board space.
Also new for e∙MMC 4.4 are heightened security features that restrict access to the phone’s critical software, such as the boot code and operating system, and provide increased security when erasing data. The full set of new features include power-on write protection, secure memory block, and secure erase, all helping to ensure that data is unaltered when transferred and stored, as well as during device reboot and power-down.

Micron’s e-MMC embedded memory combines our high-quality, low-cost NAND Flash memory with a high-speed MultiMediaCard (MMC) controller in a low-profile BGA package. e-MMC embedded memory essentially transforms a program/erase/read device with bad blocks and bad bits (NAND) into a simple write/read memory. This managed interface addresses potential NAND design concerns internally, using error correction code (ECC), wear leveling, and bad block management technology. Handling errors internally takes the burden off the host controller and increases speed, providing higher system performance.
e-MMC embedded memory simplifies hardware and software integration by providing a standard interface specification that minimizes the need for host software to accommodate process node migrations and different vendors’ NAND Flash devices. It’s a consistent, technology-independent solution that streamlines the development and qualification process and alleviates complexities of designing in current and future NAND devices.
