Yes, that should not talk about 64-bit systems but about the length of
the word the memory controller uses to create the ECC check bits out of.

That whole doc needs checking/fixing.

Well, I know it as "The syndrome field uniquely identifies the failing
bit positions of a correctable ECC error." and depending on the error
severity you can have correctable and uncorrectable syndromes.

I don't think the syndrome is the ECC word but it might be, depending
on the ECC algorithm used or it might be that what I pasted above. That
would need deeper digging.

Thx.
