Expand device development with capable
memory solutions
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-denition video play-
back 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.
To focus on these demands, developers need an efcient way
to control software development by simplifying mass storage
designs and improving device production. Developers also
require the ability to create efcient mobile device designs
with minimal costs and brief time to market. Finally, they need
superior storage capabilities to augment device production.
Samsung has a wide range of eMMC solutions based on
performance requirements.
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 benet 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.
Simplify mass storage designs
Conventional NAND Flash memory can be challenging to
adopt. Developers may have some difculty 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.
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 manage-
ment and performance optimization.
Samsung eMMC provides enhanced storage capabilities, a
reduced controller footprint and streamlined data reads and
writes. Standardized packaging and device specications plus
intelligent rmware 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.
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.

Enhanced ability to proceed directly
from concept to testing
Reduce development time and control costs
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 signicant 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.
Samsung eMMC simplies 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 rmware. This interface turns
memory accesses into straightforward read-write operations
with advanced security and reliability features.
Increase storage capabilities for diverse
applications
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-denition video playback
and other complex multimedia features. Computing power
provides booting functionality.
Samsung eMMC comprises high-density 2-bit and 3-bit MLC
NAND, and an intelligent MMC controller in a Ball Grid Array
(BGA) package.

Intelligent mobile device development
Create an ecient way to develop
well-designed mobile devices
To maintain the required data rates and throughput for
high-density chips, the eMMC standard was developed to
enhance storage capabilities, reduce controller footprint
and streamline data reads and writes. Advanced Samsung
technology helps reduce the cost of application development
and increase work efciency, enabling developers to stay
competitive by building better and faster.
Samsung eMMC contributes to successful mobile device
development. The intelligent interface is designed for ease
of use, and enhanced storage solutions improve device
designs. Samsung eMMC also helps developers go straight
from concept to testing, reducing time to market.
