JEDEC Releases Updated LPDDR5/5X SPD Standard with Enhanced Mode-Switching Support
JEDEC Solid State Technology Association, the global leader in standards development for the microelectronics industry, today announced the publication of JESD406-5D: LPDDR5/5X Serial Presence Detect (SPD) Contents standard, an update of the Revision C standard that 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.
