Solution to increasingly compact embedded systems across CIMA (Cybersecurity, Industrial, Medical and Automotive) industries with performance, endurance all packed in one.

What is eMMC designed for

Flexxon’s eMMC is designed to meet the rigid requirements of Cybersecurity, Industrial, Automotive and Medical applications where technical support, extended life, and stable roadmaps are critical.

Flexxon eMMCs product family is an embedded memory solution that combines NAND Flash memory, embedded MultiMediaCard controller, and advanced firmware in a BGA package (100 balls/153 balls). It is a compact, robust and highly cost effective NAND flash storage solution. Flexxon eMMC products are compliant with the JEDEC® e.MMC™ v4.x, v5.0 and v5.1 interface and protocol standard.

eMMC Benefit

When working with native NAND Flash components, the host system needs to actively manage data written and read at physical memory locations and correct bit errors as the data are read back from NAND Flash. Designers must implement the necessary ECC engine and data management algorithm in the host system, increasing the burden on host hardware, software design and validation. In addition, revision to the design is often required during the replacement of a NAND flash component. eMMC is a perfect solution to negate the issues as it functions as a block storage device, interacting with the host system through an abstract interface protocol.

In eMMC, the host system simply reads and writes data to and from the Logical Block Addresses. The eMMC controller hardware and firmware lifts the burden on the host system by performing error correction and data management. With the standardization by JEDEC®, Flexxon eMMC ensures compatibility and interoperability with all suppliers.

FLEXXON eMMC Intelligent Technology

Data Integrity in Reflow

Leverage strong pages from NAND flash, and prevent data loss in reflow process.

Dynamic Wear Leveling

To keep important data without moving, dynamic wear leveling could concentrate the write/erase only on the dynamic block.

System Block Protection

eMMC system information is stored in SLC area for better robustness. When FW finds UECC pages caused by sudden power loss, those pages would be discarded and move other valid data to a healthy block.

Write Reliability

After sudden power loss and next power on, eMMC will scan buffer block until last programmed page. If ECC Uncorrectable or higher ECC error bit occurs, FW will stop scanning and discard these pages, then copy valid data to new buffer block in order to save the data.

Auto Read Refresh

Good for read intensive applications. Firmware will auto-refresh the bit errors when they are approaching the pre-set threshold level.
