Key updates to this latest version of LPDDR5 include:

Speed extension up to 8533 Mbps (versus up to 6400 Mbps in the previous revision)

•Signal Integrity improvements with TX/RX equalization

•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,” according to 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.”
