Redundancy can be encoded for multiple operating points instead of hard-wiring one reliability/security tradeoff. Polymorphic Error Correction workloads=64-byte cache lines; 40-bit DDR5 channels; multiple memory fault models; baselines=fixed ECC plus MAC designs; metrics=fault correction; detection probability; MAC width; results=near-100% detection; up to 60-bit MAC; supports multiple correction modes Can one redundancy budget flexibly protect memory against different fault models while also providing strong integrity authentication? lab Make protection metadata polymorphic so systems can adapt correction strength and authentication without changing storage overhead.

Canonical title: Polymorphic Error Correction Question: Can one redundancy budget flexibly protect memory against different fault models while also providing strong integrity authentication? Context: Fixed ECC allocates check bits to one correction profile; secure memory also needs a MAC within tight metadata budgets. Method: Polymorphic Error Correction reinterprets the same redundancy across fault models, combining an inline MAC with iterative correction. Evaluation: workloads=64-byte cache lines; 40-bit DDR5 channels; multiple memory fault models; baselines=fixed ECC plus MAC designs; metrics=fault correction; detection probability; MAC width; results=near-100% detection; up to 60-bit MAC; supports multiple correction modes Interpretation: Redundancy can be encoded for multiple operating points instead of hard-wiring one reliability/security tradeoff. Reusable lesson: Make protection metadata polymorphic so systems can adapt correction strength and authentication without changing storage overhead. Applicability: Secure DDR5 memory systems combining ECC and integrity checks.
