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:

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,

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.

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

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

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 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.

Features and benefits

Create an efficient 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

ment and increase work efficiency, 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
