JEDEC has released the specifications for the new LPDDR5X memory standard. An optional extension of the general LPDDR5 standard that focuses on improving performance and flexibility of use in devices such as smartphones for which it will be especially intended.

You already know that we are waiting for the arrival of DDR5 RAM memories, once Intel and AMD have confirmed support in their next generations of processors and large manufacturers such as Samsung, Micron or SK Hynix, have already announced developments for this standard that will offer advantages in performance, power consumption, operations and also capacity compared to the current DDR4.

If DDR5 is intended to cover the section of RAM in personal computers, LPDDR5X is the low voltage variant(Low Power Double Data Rate) that will be used mainly in smartphones, wearables, automotive, virtual/augmented reality and Artificial Intelligence applications.

LPDDR5X Memory

Intended to offer increased bandwidth and a simplified architecture in support of improved 5G communication performance, the organization responsible for the standard, JEDEC, highlights three keys to the standard:

  • Expanded throughput with bandwidth up to 8,533 Mbps (up from 6400 Mbps in the previous revision).
  • Improvements in signal integrity with TX / RX equalization.
  • Reliability improvements through the new Adaptive Refresh Management feature.

Manufacturers such as Samsung who have worked in the subcommittee created by the JEDEC to bring forward the specifications of this standard, have pointed out that it is “a mobile memory interface that can provide substantial expansion of bandwidth with minimal IP change and without compromising energy efficiency”. Micron, for its part, says it will “open doors to new 5G and AI use cases, delivering better user experiences in memory-intensive applications such as gaming, photography, and media streaming.”

Less exciting than DDR5 for PCs, but another breakthrough either way for an important component like memory in an important year in new standards as we’ll also see others like PCIe 5.0 and USB4.
