Samsung eMMC
Managed NAND Flash memory solution supports mobile applications
FBGA QDP Package
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-den-
sity content storage that supports high-definition video
playback and other high-end multimedia features. As a
result, memory densities are advancing at rapid rates.
• Robust.Today’s fastest and most demanding embed-
ded uses require strong memory management solu-
tions. Embedded uses include multifunctional smart-
phones, portable media players and tablet computers.
• Small.The Joint Electron Device Engineering Council
(JEDEC) requires memory to be produced in extremely
compact sizes to allow space for other components.
To focus on these demands, developers need an efficient
way to control software development by simplifying mass
storage designs and improving device production. Develop-
ers 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.
Simplify mass storage designs
Conventional NAND Flash memory can be challenging to
adopt. Developers may notice difficulty controlling software
development, particularly when implementing wear level-
ing, bad block management, device mapping and error
handling. Developers may also experience 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, in-
cluding tablets, smartphones, GPS systems and e-readers.
Chipset validation means that eMMC is a thoroughly tested
solution. Samsung eMMC incorporates a standard, mature
interface 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 specifica-
tions plus intelligent firmware ease design work and provide
a common footprint for the use of embedded and remov-
able 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 (4 GB or 8 GB) to high (16 GB, 32 GB, 64 GB
or 128 GB) density requirements.
Samsung embedded multimedia card (eMMC) addresses
these needs with advanced embedded NAND Flash. It helps
simplify mass storage designs for the latest consumer elec-
tronics. Samsung eMMC is produced in very compact sizes
(typically smaller than a postage stamp) to create room
within devices for additional parts. Key application areas
that can leverage 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.

Reduce development time and control costs
In the past, a product using NAND memory required chang-
es 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 for
product-level testing. In contrast, developers using
Samsung eMMC can move forward directly from product
concept to product testing. Samsung eMMC isolates the
host from changes in NAND memory technology and by-
passes the FTL, which reduces design, development and
testing time, and helps control costs.
Samsung eMMC incorporates simplified system design and
integration of multi-level cell (MLC)-type NAND 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 oper-
ates at standard 4.41 and 4.5 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.

concept directly to product testing.
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-definition
video playback and other complex multimedia features.
Computing power provides booting functionality.
Samsung eMMC comprises high-density MLC and TLC
NAND, and an MMC controller in a Ball Grid Array (BGA)
package. It supports x1, x4 or x8 bus widths and interface
voltages of 1.8 V or 3.3 V.
