eMMC Explained: The Key to Flash Storage in Your Devices

The term eMMC stands for embedded Multimedia Card. It refers to a package comprising flash memory and a flash memory controller incorporated on a similar silicon die.

The eMMC component contains at least three elements: the multimedia card interface, flash memory, and the flash memory controller.

This component is offered in an industry-approved Ball Grid Array package.

Where Can eMMC Be Used?

eMMC is smaller than a typical postage stamp. Its tiny footprint makes it suitable for many electronic devices, such as small laptops, smartphones, wearable technology, smart TVs, and intelligent home appliances.

The word embedded comes from the fact that the storage is fixed directly onto the device’s motherboard, so it can’t be removed or displaced easily.

eMMC storage includes NAND flash, which can be found in devices such as SD cards, USB drives, and solid-state drives, but it is packaged differently.

Aside from its services in consumer products, eMMC can also be employed in several other embedded applications, which may include robotics, Single-Board Computers, automotive, networking, medical devices, and control device development.

This results from its compact size, limited power consumption, and multiple enhanced features.

The application of eMMC has become broader because of the advancement of the IoT market.

How Does eMMC Work?

The eMMC is fixed by connecting it directly to the central circuit board of a device where it stores data.

Using an integrated controller in the eMMC, the CPU does not have to transfer data into storage since the controller in the eMMC takes over that process.

This activity allows the CPU to handle other significant tasks. When flash memory is used, IC-based storage uses little power, which makes it appropriate for portable devices.

Increased Capacities and Small Footprint

eMMC capacities vary from 1GB to 512GB, and it comes in various grades depending on its use (i.e., consumer & industrial).

The most popular eMMC storage capacities are 32GB and 64GB, and they use 3D MLC or SLC NAND flash.

Hence, it is suitable for heavy-duty applications and is highly dependable. Considering its size, eMMC can handle vast amounts of data in a small footprint.

Is eMMC Suitable for Developers?

eMMC streamlines the interface design and capability process. This causes a decrease in market time and facilitates the support of flash devices that are yet to be manufactured.

The primary interface of an eMMC makes the fast-changing NAND technology invisible to the host.

This means the host processor doesn’t always have to change its software to accommodate every NAND technology modification and variation.

It also helps to reduce the design-in complexity and shorten the qualification cycle.

What Are the Differences Between Industrial and Consumer eMMC?

There has been news that eMMC boots slowly. This isn’t true, as we currently have a few eMMC solutions that can begin booting in less than 10ms.

This allows eMMC to be employed as data storage and a NOR flash substitute for boot code.

It makes the eMMC a more desirable recommendation for developers developing small systems.

Although industrial and consumer eMMC may look similar inside and out, industrial eMMC can be customized to improve its performance for the application.

This table summarizes the crucial dissimilarities between industrial and consumer eMMC.

Before buying any eMMC products, consult with an expert to confirm that you are selecting the right variety for your appliances. This will help you avoid unnecessary expenses.
