# DDR4 SPD tools README
Tools for generating SPD files for DDR4 memory used in memory down
configurations on Intel Tiger Lake (TGL) based
platforms. These tools generate SPDs following JESD79-4C
Tools for generating SPD files for DDR4 memory used in platforms with
memory down configuration. These tools generate SPDs following JESD79-4C
and Jedec 4.1.2.L-5 R29 v103 specifications.
There are two tools provided that assist TGL based mainboards
to generate SPDs and Makefile to integrate these SPDs in coreboot
build. These tools can also be used to allocate DRAM IDs (configure
DRAM hardware straps) for any DDR4 memory part used by the board.
