제목	Polymorphic Error Correction
궁금했던 점	Can one redundancy budget flexibly protect memory against different fault models while also providing strong integrity authentication?
해본 것	Polymorphic Error Correction reinterprets the same redundancy across fault models, combining an inline MAC with iterative correction.
당시 조건	Venue: MICRO. Year: 2024. Fixed ECC allocates check bits to one correction profile; secure memory also needs a MAC within tight metadata budgets. Verification: official_abstract; confidence=medium.
실제 결과	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
왜 그랬는지	Redundancy can be encoded for multiple operating points instead of hard-wiring one reliability/security tradeoff.
다음에 기억할 것	Make protection metadata polymorphic so systems can adapt correction strength and authentication without changing storage overhead.
언제 맞는지	Secure DDR5 memory systems combining ECC and integrity checks. Limits: Assumes a MAC+ECC secure-memory setting; performance, iteration latency, and all fault assumptions were not verified from full text.

Verification: official_abstract; confidence=medium. 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. Limits: Assumes a MAC+ECC secure-memory setting; performance, iteration latency, and all fault assumptions were not verified from full text.
