That's the idea. ECC can correct single bit errors and detect (but not
correct) 2 bit errors.
Compaq's memory design on their serers has ECC-2 which corrects 2 bit errors
and can detect (but not correct) 4 bit errors. I don't know how common ECC-2
is among server designs from other companies...
Typically, such things are considered of less importance on a workstation,
which is also why you don't find RAID (or even SCSI) on many workstations
either...
