I was thinking about doing error correction in software at driver/kernel level as opposed to using ECC RAM.
Even though ECC contains the logic of doing error correction in one chip, that doesn't justify double prices.

- toast0 4y agoAs a sibling said, rhis would certainly come at a huge performance cost. Inline/Inband ECC is showing up again recently, which might be of interest. It comes at a performance cost too, but basically you use regular RAM, and the memory controller issues extra read/writes for the ECC data separately from the rest of the data for a given address. If that gains traction, it could bring ECC to the masses.
