JEDEC’s Updated LPDDR5/5X SPD Standard Features Enhanced Mode-Switching Support


Thursday, March 26, 2026

JEDEC Solid State Technology Association’s JESD406-5D: LPDDR5/5X Serial Presence Detect (SPD) Contents standard, an update of the Revision C standard, adds support for calculating recovery time when switching operating modes.

JESD406-5D is available for free download from the JEDEC website.

LPDDR5/5X memory devices are capable of supporting two sets of timing parameters: a full speed mode and a reduced speed mode that consumes less power. This feature allows for longer battery life for mobile devices which are a common application for LPDDR5/5X chips and modules and may also be leveraged by data centers as the use of LPDDR5/5X devices grows. The updated JESD406-5 standard documents key parameters for calculating the switching time between fast and low power modes, making the feature more efficient and allowing higher system performance.

“Reducing power consumption has become imperative for computing systems as the use of AI and other demanding applications accelerate,” said Bill Gervasi, Chair of the JEDEC SPD Task Group. “The updates to the JESD406-5 standard are an important enabler for systems to optimize performance while maintaining a lower power profile.”
