BL> In a general sense, I never did see any point in parity. If a system
BL> is so unreliable it needs 12.5% redundancy then 12.5% is not enough!
BL> The minimum workable redundancy is 100% - or you may as well not bother.

PE> It isn't redundancy, it's designed to see if an
PE> error has occurred, ie the memory has been corrupted.

BL> How does that work? If the other 8 chips handle one bit each,
BL> then how does the one-bit in the parity chip keep track on 8?
BL> I assumed that it had to work on averages... a false parity
BL> meant it was likely one of the others had failed too.

He's just doing more completely senile mindless coat trailing.
