Managed NAND Flash memory solution supports mobile applications

Samsung 

Efficiency, reduced costs and quicker

time to market

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.

Samsung has a wide range of eMMC

solutions based on performance

requirements.

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.

NAND Flash memory

eMMC interface

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.
