Introduction to eMMC-“embedded MultiMediaCard”:

Embedded MultiMediaCard (eMMC) is a storage solution for compact embedded systems employing a non-volatile NAND flash memory, mitigating the requirement of a constant power source for the retention of data and a flash memory controller integrated on the same silicon die. The eMMC solution consists of three components: the MMC (multimedia card) interface, the flash memory, and the flash memory controller, and it is offered in an industry-standard BGA (Ball Grid Array) package. The “embedded” part portrays the direct soldering of the MultiMediaCard onto the device’s motherboard making it non-displaceable or immovable.

Usability of eMMC:

Smaller hardware than a typical postage stamp, tiny footprint and cost-effectiveness of eMMC storage renders it ideal for a market of multiple devices, including smartphones, tablets, budget PCs, laptop, smart home appliances, smart TVs, wearable technology, electronic learning products, eBook readers, infotainment, wearable technology digital setup boxes and cameras. Apart from its use in consumer products, eMMC is swiftly being appropriated in many other industrial and automotive embedded applications, such as robotics, GPS systems, Single Board Computers (SBC), medical devices, networking, building control devices, aerospace, defense, healthcare, public, Information technology, telecom, CCTV, surveillance, home automation, Light Vehicle Display, Agricultural machinery and point-of-sale systems because of its small-scale size, stunted power consumption and several intensified features. Furthermore, eMMC is also uncovering a path in IoT applications with the expeditious growth of the IoT market. The surge in the rise of electronic devices and the high demand for integrated memory in mobile computing devices has boosted the development of the global embedded multimedia card market. According to Global Info Research’s latest study, due to the COVID-19 pandemic, the global Embedded Multimedia Card (eMMC) market is estimated to be worth US$ 6328.8 million in 2022. It is forecasted to reach US$ 7513 million by 2028 with a growing positive CAGR of 2.9%.

The need for high-density, high-tech, cost-effective, low-power consumption, and compact-sized, non-volatile memory solutions with a small footprint has increased dramatically. Being a manufacturing leader of NAND Flash storage devices and realizing the demand, FLEXXON proposes a high-performance, reliable and robust eMMC embedded memory solution that combines eMMC NAND Flash memory, embedded MultiMediaCard controller, and advanced firmware in a BGA package (100 balls & 153 balls) offering longer life cycles with power management. FLEXXON eMMC products are compliant with the JEDEC® eMMC™ v5.1, v5.0, v4.x interface and protocol standards supporting features such as boot operation, replay protected memory block (RPMB), device health report, field firmware updates, power-off notification, enhanced features for faster and more reliable operation, write leveling, high-priority interrupt (HPI), secure trim/erase, and high-speed. FLEXXON’s eMMC is incorporated with the SMART feature, which stands for Self-Monitoring Analysis and Reporting Technology, allowing users to monitor the status of their device’s performance, reliability, health monitoring and control. The eMMC supports Linux commands to read the SMART information from the device and examine the quality of health as well as the remaining life of the eMMC to avoid grave failures. The Global Embedded MultiMediaCard (EMMC) Market Growth Report has nominated FLEXXON as one of the prominent eMMC manufacturers. FLEXXON supports both eMMC 100 balls and eMMC153balls variants. The market mainstream now is eMMC 153 balls which is suitable for industrial applications, FLEXXON also offers customizable services in eMMC product,its eMMC 100 balls supports functionality in small and low-power electronics, acting as a versatile device manufacturer encompassing wider applications needs of the market.

Functionality of FLEXXON’s eMMC:

The host system has to vigorously manage data write/read operation at physical memory locations, correct bit errors as the data is read back from NAND Flash and revise the design during the replacement of a NAND Flash component. This necessitates the implementation of the ECC engine and data management algorithm in the host system, increasing the burden on host hardware, software design and validation. FLEXXON’s eMMC Storage is an ideal storage alternative to negate these issues as it functions as a block storage device, interacting with the host system through an abstract interface protocol. A direct parallel connection is established between the FLEXXON’s eMMC IC and the main circuit board of the device for which it stores data. The integrated controller and firmware of FLEXXON’s eMMC take over the function of handling the placement of data storage and performing error correction, freeing up the CPU for more important tasks. The host system simply reads and writes data to and from the Logical Block Addresses. The built-in controller transforms the FLEXXON’s eMMC into a bootable storage device to be used as a system drive inside the host interface. Moreover, the flash memory operation of the entire miniaturized IC-based FLEXXON’s eMMC storage draws little power consumption compared to a spinning disk.

Significant Features of FLEXXON’s eMMC:

The FLEXXON’s eMMC provides a decent amount of storage in an affordable and lightweight form. Its compact size makes it suitable for smaller consumer devices, tiny sensors and control devices. Unlike some other types of flash memory, an eMMC is bootable, allowing laptop makers to manufacture laptops with internal flash storage. With the standardization by JEDEC®, FLEXXON’s eMMC ensures compatibility and interoperability with suppliers and is an embodiment of endurance and consistency in various fields, exhibiting the following features:
  • Tailor-made firmware: The firmware warrants the use of eMMC according to the nature of the application.
  • Highly Integrated eMMC Solution: Exceptional storage capacity of 4GB to 512GB supports an extensive temperature range of -25°C ~ 85°C.
  • Packaged Design: Compact-sized storage device to meet various applications’ high reliability and high-performance needs.
  • Data Integrity in Reflow: Leverage strong pages from NAND flash, and prevent data loss in the reflow process.
  • Dynamic Wear Leveling: To guarantee data integrity during movement, dynamic wear leveling could concentrate the write/erase only on the dynamic block.
  • Auto Read Refresh: Good for read-intensive applications. Firmwares will auto-refresh the bit errors approaching the pre-set threshold level.
  • Write Reliability: After sudden power loss and the subsequent power on, eMMC will scan the buffer block until the last programmed page. If an ECC Uncorrectable or higher ECC error bit occurs, FW will stop scanning and discard these pages, then copy valid data to a new buffer block to save the data enhancing write protection.
  • System Block Protection: System information is stored in the SLC area for better robustness. During sudden power loss, the FW recognizes data loss in UECC pages. The system block protects those pages from being discarded and moves the valid data into a healthy block.
  • Advanced NAND management: RoHS Compliance ensures superior quality NAND management, and controlled BOM ensures consistent performance.
  • SMART: FLEXXON’s eMMC supports the Linux command to read the SMART information and monitor the health and remaining life of the eMMC to avoid critical failures.
