128-bit unique chip identifier

According to the Reference Manual Rev. 7, Chapter 2.2 Feature Set, the device supports a "128-bit unique chip identifier". However, the only unique chip identifier I found so far is the 64-Bit long "Device Unique ID" in the fuses (OCOTP_CFG0 and OCOTP_CFG1). Is there another unique ID or is the feature set wrong about the length of this unique chip identifier?
