DDR5 Serial Presence Detect (SPD) ContentsTerminology update Release Number: Version 1.1 |
JESD400-5A.01 | Jan 2023 |
This standard describes the serial presence detect (SPD) values for all DDR5 memory modules. In this context, “modules” applies to memory modules like traditional Dual In-line Memory Modules (DIMMs) or solder-down motherboard applications. The SPD data provides critical information about all modules on the memory channel and is intended to be used by the system's BIOS in order to properly initialize and optimize the system memory channels.
