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.
