Storage is a crucial part of any embedded system, especially given the level of intelligence and features manufacturers are embedding into smaller devices.
A Memory management controller (MCU) is a cost-effective way to manage all system memory in an embedded device. eMMC integrated circuit (IC) is often known as an embedded multimedia card or Embedded Multi-Media Controller. It’s actually a computer chip that has many functions, which makes it useful for almost any kind of small computer system. In this article, we will explain everything you need to know about eMMC IC.
What is eMMC IC and what does it do?
eMMC stands for embedded multimedia memory card. It’s actually a computer chip that has many functions, which makes it useful for almost any kind of small computer system.
It’s a self-contained device that can fit in a tiny chip, making it easy to place almost anywhere.
And with the right programming, you can access data on the eMMC chip just like you would on a normal hard drive.
eMMC is usually implemented as a small removable card that plugs into a dedicated slot on the system.
It’s used in a number of devices, including smartphones, computers, digital cameras, tablets, and other devices.
What is the purpose of eMMC?
The purpose of eMMC is to provide a standardized and low-cost storage option for embedded systems.
The eMMC IC manages non-volatile storage, data integrity, and security in an embedded device.
It also manages the user interface, data logging, and even software upgrades.
The eMMC IC lets you store all your software and data in one place, making it easy to update and manage the device.
Structure and functionality of eMMC
What does an eMMC look like and how is it able to function?
To find the answer, we will have to look at the physical structure and design of this storage device.
In terms of appearance, it looks like a small memory card or a USB flash drive.
The size of the memory module can vary depending on the manufacturer, but in general, it is about 15 mm x 11 mm x 1.5 mm thick and has a capacity of 8 GB to 64 GB.
Controller – manages all operations with data; Flash memory – stores all your data; Voltage regulator – provides power to the entire module; Connector – allows you to connect the module to a device or computer; JTAG connector – allows you to connect a special adapter and access all information on the eMMC chip.
eMMC memory is similar to other flash memory, but with one important difference.
It has an embedded controller that manages the memory and makes it easier to use.
The controller is responsible for controlling the reading and writing of data and acts like a ROM controller, ROM being a non-volatile memory. eMMC memory is designed to be used in small embedded computers that don’t have the space or resources to use a full-blown computer. It is typically used as the primary storage device in embedded systems and is connected to the host computer through a standard interface such as a USB port.
eMMC IC working principle
How does the eMMC integrated circuit work?
This storage chip is able to execute its functions majorly because of two key components.
These are the controller and the NAND flash memory.
Keep in mind that both these components exist within the integrated circuit chip.
The IC, which contains the two components then connects to the main device that you are using.
It can be a computer, mobile device, or any other high-level device.
The controller of the eMMC IC is responsible for feeding data into the storage.
The size of data to be stored will depend on the capacity of the eMMC.
This is why when buying this chip, it is important to consider its storage capacity and even your operational data capacity.
Since the data has been stored, the CPU of the device that you are using will focus on executing other essential or sensitive tasks and responsibilities.
Can I use eMMC as a separate memory device?
You can use an eMMC as additional storage space for your computer, smartphone, or tablet.
You can also install it on any device that has an SD card slot, such as digital cameras and other devices with removable storage.
In addition, you can install it yourself if you have basic skills in repair and assembly of electronic devices.
If you want to do this, then be sure to buy only original equipment (OEM) modules with good technical characteristics and long warranty period (up to two years).
To access information from an eMMM module using standard computer hardware tools, we need special adapters that allow us not only read information from it but also write new data.
In addition, there are several special software tools that make it possible to recover information from eMMC memory and restore deleted files.
Key Features of eMMC IC
– Low cost – eMMC is often used in cheap devices, but is also used in expensive devices such as cellphones and tablets.
– Low power consumption – The operating voltage of eMMC IC is 5V, which is low enough to be powered by a single AA or AAA battery.
– Reliability – eMMC IC is more reliable than other types of flash memory, making it a good option for devices that are used heavily and stored for extended periods of time.
– Uses a standard interface – eMMC IC uses a standard, industry-standard interface such as USB, SD Card, or SATA for connecting it to a host computer.
– System scalability – eMMC IC supports hot plugging, which allows you to access the data on the device without turning off the power.
-Compact size and design- eMMC IC is small enough to fit in the palm of your hand, and has a storage capacity of up to 512GB.
– Fast read and write speeds – eMMC supports fast speed data transfer via its built-in DMA controller.
– Supports booting from flash memory – eMMC supports booting from flash memory, allowing you to use it as a programmable ROM device.
Limitations of eMMC IC
Speed-The main limitation associated with eMMC is speed. eMMC is slower than other types of non-volatile memory, such as SRAM and flash memory. Because of its slower speed, eMMC is not suitable for applications that require fast data transfer rates.
– Small storage capacity – The storage capacity of eMMC is limited to 512GB, which may not be sufficient for applications that require a large amount of storage space.
– Limited number of I/O pins – The number of pins available on an eMMC IC is limited to 20 pins. This makes it difficult to use eMMC in applications that have a large number of I/O pins.
Technical specifications of eMMC IC
– Storage capacity – The storage capacity of eMMC ICs vary, but the typical capacity is 32GB though it can go uo to 32GB
– Interface – eMMC ICs use standard interfaces like USB, SD, or SATA.
– Operating temperature- The operating temperature of eMMC ICs vary, but they can operate at temperatures as low as -40°C and as high as 85°C.
– Data retention – eMMC ICs have a finite lifespan and will eventually wear out.
How fast is eMMC IC?
Speed is one of the key issues that we have constantly mentioned in the article.
How fast is it?
According to the Windows Central website, eMMC ICs have the capacity of hitting transfer speeds of up to 400Mbs/s.
While this figures may appear impressive, this does not negate the fact that an average eMMC is still lower than most of its alternatives.
The good news is manufacturers have been [putting serious efforts towards improving the transfer speeds of eMMC.
Other factors to look for when buying eMMC IC
– ECC : Error-correcting code (ECC) is a data-correction mechanism used in computers to reduce the number of incorrect bits in data transmission. It can be used in a flash memory controller to correct bit errors.
