Notes: 1. All serial PD data are not protected. 0: Serial data, “driven Low”, 1: Serial data, “driven High” These
SPD are based on JEDEC Committee Ballot JC-42.5-99-129.
2. Byte72 is manufacturing location code. (ex: In case of Japan, byte72 is 4AH. 4AH shows “J” on ASCII
code.)
3. Bytes 95 through 98 are assembly serial number.
4. All bits of 99 through 127 are not defined (“1” or “0”).
5. These specifications are defined based on component specification, not module.
