What Is eMMC?

Delkin Devices Industrial eMMC

 

Embedded multimedia controllers, or eMMCs, are a type of flash memory card that contain the flash memory and flash memory controller on a single die. They are frequently used in portable electronic devices that need flash memory, but don’t have space for separate flash memory and controllers. Having the combination of both memory and controller on a single die saves space in these devices. However, eMMC is not the right solution for every application, and there can be issues using it in some industrial devices. Here is what you need to know.

 

eMMC Explained

eMMC tends to be selected for embedded memory in devices that have limited space and where developers need to keep prices low. As such, they are typically found in lower-priced computers, mobile phones, and tablets. They are also sometimes used as an additional form of storage in devices that already have embedded storage of another format. The size is a major advantage of eMMC, and when engineers outside of the consumer market are considering eMMC for storage, it is usually because they are working with a device that has constrained space. This kind of storage has a long history of being used in electronic devices. It actually existed before SD cards and can be used in many of the same places SD cards can, with the caveat that SD cards are available in different flash grades.

 

eMMC versus SSD

Typically, for industrial devices, engineers go for flash memory in the form of SSDs or industrial grade SD cards. The reason for this is the reliability that these kinds of flash memory provide. Industrial grade flash memory is usually designed with SLC, or single-level cell, flash memory. This kind of flash memory is tolerant of extreme operating conditions, particularly in terms of temperature, shock, and vibration. It also offers the highest level of data security. Additionally, SLC flash is the fastest available form of flash memory, which is critical for industrial operations. SSDs, with separate flash controllers, also provide integrated error correction, which eMMCs are not capable of delivering. As such, in industrial applications in which failures can be extremely costly and even dangerous, most engineers opt to choose something other than eMMC for embedded storage.
