DDR5 SERIAL PRESENCE DETECT (SPD) CONTENTSRelease Number: Release 1.3 |
JESD400-5C | Sep 2024 |
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 use by the system's BIOS in order to properly initialize and optimize the system memory channels.

SPD5118 HUB and SERIAL PRESENCE DETECT DEVICE STANDARDRelease Number: Version 1.5.1 |
JESD300-5B.01 | May 2023 |
This standard defines the specifications of interface parameters, signaling protocols, and features for DDR5 Serial Presence Detect EEPROM with Hub function (SPD5 Hub) and integrated Temperature Sensor (TS) as used for memory module applications. The Hub feature allows isolation of a local bus from a Controller host bus. The designation SPD5118 or generic term SPD5 Hub refers to the devices specified by this standard.

Annex M: Serial Presence Detect (SPD) for LPDDR3 and LPDDR4 SDRAM Modules, Release 1Release Number: 25 |
SPD4.1.2.M-1 | Nov 2015 |
Committee Document Reference Title: LPDDR3 and LPDDR4 SPD Document Release 1 This Annex describes the serial presence detect (SPD) values for all LPDDR modules. Differences between module types are encapsulated in subsections of this annex. These presence detect values are those referenced in the SPD standard document for ‘Specific Features’. The following SPD fields will be documented in the order presented in Section 2, with the exception of bytes 128~255 which are documented in separate sections, one for each family of module types. Further description of Byte 2 is found in Annex A of the SPD standard. Item 2254.01 Committee(s): JC-45 JESD21-C Solid State Memory Documents Main Page Free download.
