Notes: 1. All serial PD data are not protected. 0: Serial data, “driven Low”, 1: Serial data, “driven High”
These SPD are based on Intel specification (Rev.1.2A).
2. Regarding byte32 to 35, based on JEDEC Committee Ballot JC42.5-97-119.
3. Byte10, 23, 24, 32 through 35 are component spec.
4. Byte72 is manufacturing location code. (ex: In case of Japan, byte72 is 4AH. 4AH shows “J” on
ASCII code.)
