>>Pairty modules do have 8 bits of parity for 8 bytes in PC's

I guess it depends on how you define parity dimms. Before ECC, parity simms usually mean odd/even bit parity (single bit). Now the parity dimms are actually multi-bits so it is no doubt capable to handle error-correction.

Now the next question, so what the difference between the parity dimm and ECC dimm? Or are we really talking about the same thing?

Thanks Spots, Sean and Dave

BTW, that ECC is very clever. I must look it up again.
I remember being impressed and delighted when I first
saw it (and that's about ALL I remember <g>).



Here's a good reference from the a MIPS Cpu Manual.

This is the algorithm most common used in hardware....
