I agree. There is no reason for ECC to not be the norm. And once scaled up, it would be as cheap as regular RAM.

- AlexandrB 9y agoI'm not sure that would ever be the case. To get ECC you're adding 1/8 extra SDRAM to a memory module to hold the parity bit. That same extra SDRAM could just be used as system memory without ECC giving you 1/8 extra RAM for the same components/price.
- monocasa 9y agoWhat I'm hoping doesn't happen is that RAM manufacturers start relying on ECC, shipping partially bad chips that'll have their problematic areas transparently fixed by ECC. I could see that increasing yield enough to account for increased die space. There's an non trivial chance that they already do this for LPDDR where the bit lanes aren't spread across chips.
