Flexxon designs, manufactures and markets Industrial NANO Flash Storage Solutions products, serving specifically the INDUSTRIAL, MEDICAL & AUTOMOTIVE (IMA) applications and customers worldwide, who demand the very highest level of reliability, endurance and wide operating temperature ranges
The trend of the size of embedded systems continues to shrink in some industrial and medical applications. There is a need for even smaller form factor storage than microSD card.
Flexxon eMMC's design to meet the rigid requirements of IMA (Industrial/ Medical/ Automotive) market where technical support, extended life, and stable roadmaps are critical for this segment industry.
Flexxon eMMC Product Family is an embedded memory solution that combines NANO Flash Memory, an embedded MMC (MultiMediaCard) controller, and advanced firmware in a small BGA package (100 balls/ 153balls/ 169 balls ) that provides a small, robust, yet cost effective, high density embedded NANO Flash storage solution. The eMMC products are compliant to the JEDEC eMMC v4.5 and vS.O interface and protocol standard.
When working with native NANO Flash components, data are written and read directly to physical locations in the NANO Flash memory. Host system needs to actively manage data at physical memory locations and correct bit errors as the data are read back from NANO Flash. Designers must implement the necessary ECC engine and data management algorithm in the host system, increasing the burden on host hardware and software design and validation. Revision to the design may be necessary each time the NANO Flash component is replaced by a newer part or a part from a different vendor. In comparison, eMMC functions as a block storage device, interacting with the host system through an abstracted interface protocol, analogous to an SSD. The host system simply writes and reads data to and from logical block addresses (LBA's), without needing to anticipate data errors and how the data would be stored and managed in the NANO Flash memory. The eMMC controller hardware and firmware handles the error correction and data management functions internally without involvement from the host system. Since the eMMC interface and protocol standardized by JEDEC® is agnostic to the underlying NANO Flash memory technology and configuration, compatibility and interoperability among different suppliers' eMMC products can be assured.
