LPDDR5 and LPDDR5X will significantly boost memory speed and efficiency for a variety of uses including mobile devices and AI applications.
JEDEC Solid State Technology Association has published the JESD209-5B, Low Power Double Data Rate 5 (LPDDR5), which includes both 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.
Taken together, LPDDR5 and LPDDR5X are designed to significantly boost memory speed and efficiency for a variety of uses including mobile devices, such as 5G smartphones and artificial intelligence (AI) applications. Developed by JEDEC’s JC-42.6 Subcommittee for Low Power Memories, JESD209-5B is available for download from the JEDEC website.
Key updates to this latest version of LPDDR5 include speed extension up to 8533Mbps (versus up to 6400Mbps in the previous revision); signal integrity improvements with TX/RX equalization; and reliability improvements via the new Adaptive Refresh Management feature.
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,” said Mian Quddus, JEDEC’s Chairman of the Board of Directors. “But a power-conserving solution that will set the bandwidth bar considerably higher in taking 5G into a wider consumer embrace worldwide.”
