JEDEC is the global leader in the development of standards for the microelectronics industry. Thousands of volunteers representing over 300 member companies work together in more than 100 JEDEC committees and task groups to meet the needs of every segment of the industry, manufacturers, and consumers alike. The publications and standards generated by JEDEC committees are accepted throughout the world.

JEDEC’s new and updated standards for low power memory devices will be used in 5G and AI applications. An update to the LPDDR5 standard that is focused on improving performance, power, and flexibility, and a new LPDDR5X standard, which is an optional extension to LPDDR5. Key updates to this latest version LPDDR5X include:

The new LPDDR5X component of JESD209-5B is an optional extension intended to offer higher bandwidth and simplified architecture in support of enhanced 5G communication performance and is designed for applications ranging from automotive to high resolution augmented reality/virtual reality and edge computing using AI.

As one of the fastest memories in recent memory to move from concept to industry standard, LPDDR5x is not only a turbo-charged pacesetter for the smartphone marketplace but a power-conserving solution that will set the bandwidth bar considerably higher in taking 5G into a wider consumer embrace worldwide.

Mian Quddus, JEDEC’s Chairman of the Board of Directors.

As a leader in low-power memory, Micron collaborated closely with other JEDEC members to define LPDDR5X, providing the mobile ecosystem a critical advancement in higher bandwidth. LPDDR5X’s higher-speed interface will open doors to new 5G and AI use cases, delivering better user experiences across memory-intensive applications such as gaming, photography, and streaming media.

said Osamu Nagashima, Micron senior manager of mobile systems architecture and vice-chair of the JEDEC low power memories subcommittee.

Samsung has joined with others on JEDEC’s JC-42.6 subcommittee in standardizing one of the most eagerly anticipated memory advancements in quite some time — a mobile memory interface that can provide substantial bandwidth expansion with minimal IP change and without compromising power efficiency. In lockstep with JEDEC’s LPDDR5/5X standardization process, Samsung also has been working closely with leading manufacturers to pave the road for the next generation of smartphones, laptops, and other mobile computing devices.
