Samsung eMMC Managed NAND Flash memory solution supports mobile applications FBGA QDP Package BROCHURE High efficiency, reduced costs and quicker time to market Expand device development with capable memory solutions Simplify mass storage designs Conventional NAND Flash memory can be challenging to adopt. Developers may have some difficulty controlling software development, particularly when implementing wear leveling, bad block management, device mapping and error handling. Developers may also encounter issues related to die shrinkage, including page size and error correcting code (ECC) management. To meet current trends for advanced mobile device designs, manufacturers require memory that is increasingly dense, robust and small: * Dense. Sophisticated mobile devices require high-density content storage that supports high-definition video playback and other high-end multimedia features. As a result, memory densities are rapidly advancing. * Robust. Today's fastest and most demanding embedded uses require strong memory management solutions. Embedded uses include multifunctional smartphones, portable media players and tablet computers. * Small. The Joint Electron Device Engineering Council (JEDEC) encourages memory to be produced in extremely compact sizes to allow space for other components. Conversely, Samsung eMMC is designed to be easy to adopt. It is suitable for the latest consumer electronics, including tablets, smartphones, GPS systems and e-readers. Chipset validation means that eMMC is a thoroughly tested solution. Samsung eMMC incorporates a mature interface standardized by JEDEC, and key functionality yields strong power management and performance optimization. Samsung eMMC provides enhanced storage capabilities, a reduced controller footprint and streamlined data reads and writes. Standardized packaging and device specifications plus intelligent firmware ease design work and provide a common footprint for the use of embedded and removable NAND. Samsung offers a single footprint combining boot, embedded storage and external mass storage in one device. To focus on these demands, developers need an efficient way to control software development by simplifying mass storage designs and improving device production. Developers also require the ability to create efficient mobile device designs with minimal costs and brief time to market. Finally, they need superior storage capabilities to augment device production. In addition, Samsung offers a wide range of eMMC solutions based on low (4GB or 8GB) to high (16GB, 32GB, 64GB or 128GB) density requirements. Samsung has a wide range of eMMC solutions based on performance requirements. NAND Flash memory eMMC interface HOST interface layer Samsung embedded multimedia card (eMMC) addresses these needs with advanced embedded NAND Flash. The eMMC helps simplify mass storage designs for the latest consumer electronics. Samsung eMMC is produced in very compact sizes (typically smaller than a postage stamp) to create room within devices for additional parts. Key applications that can benefit from Samsung eMMC include advanced mobile devices and handsets. These products use eMMC to expand computing power and content storage. They also use eMMC to provide booting functionality. Flash transfer layer Virtual address Virtual Flash layer Physical address Flash interface layer NAND Flash memory Figure 1. MMC user BROCHURE 2 Enhanced ability to proceed directly from concept to testing Reduce development time and control costs Increase storage capabilities for diverse applications In the past, a product using NAND memory required changes in the chipset or the OS. At times, the NAND memory also required changes to be made in the Flash translation layer (FTL). The changes then needed to be tested at the NAND level, which could lead to significant delays in product-level testing. In contrast, developers using Samsung eMMC can move directly from product concept to product testing. Samsung eMMC isolates the host from changes in NAND memory technology and bypasses the FTL, which reduces design, development and testing time, and helps control costs. Advanced mobile devices and handsets can use Samsung eMMC to expand computing power and content storage. Enhanced storage solutions for mobile devices that provide high-density solid state memory can be integrated into system designs. Traditional storage media, as a result of the high storage capacity of eMMC, can be replaced by lower-power solid-state drives (SSDs). Including SSDs enables increased storage densities, reduced costs and low power consumption. Content storage supports high-definition video playback and other complex multimedia features. Computing power provides booting functionality. Samsung eMMC simplifies system design and integration of 2-bit and 3-bit multi-level cell (MLC)-type NAND memory, and triple-level cell (TLC) memory, leading to faster overall time to market. This approach makes Samsung eMMC memory an excellent choice for deployment across a variety of segments, including low-cost legacy chipsets. Samsung eMMC operates at standard 4.41, 4.5, and 5.0 voltage levels, so there is no need to develop or use separate firmware. This interface turns memory accesses into straightforward read-write operations with advanced security and reliability features. Samsung eMMC comprises high-density 2-bit and 3-bit MLC NAND, and an intelligent MMC controller in a Ball Grid Array (BGA) package.
