Maybe you're thinking of the error correction controller that's on the module now? Memory with inline encryption is not very common, and as far as I know, not actually very secure if the CPU/TPM isn't the one holding the encryption key. permalink fedilink source parent hideshow 1 child comment replies: [–] Lojcs@piefed.social 2 points 4 months ago* Right, that was what it was ty permalink fedilink source parent
