No, it is not built to handle RAM errors.  Once the data has been 
decoded, checked, and put in the zfs ARC (huge memory cache) then the 
data can be corrupted in RAM and nothing is likely to notice.

Likewise, data which is written may be corrupted if it is corrupted 
before the zfs checksums are computed.
