By reformatting it, you've successfully obscured what typos you've fixed.
As a result I read the whole paragraph, and ...

Usually a 64-bit system refers to the width of a pointer. Here, it's
referring to the width of the memory system, which is rather confusing.
How about "In the above example" instead of "So, on 64 bit systems".

This would read better as:
The extra 8 bits which are used for error detection and correction
are referred to as the *syndrome*\ [#f1]_\ [#f2]_.
