Abstract

Embodiments of the invention are generally directed to systems, methods, and apparatuses for mitigating silent data corruption using an error correction code having embedded signaling fault detection. In an embodiment, a memory controller includes an extended error correction code (ECC) and link signaling fault detection logic. The extended ECC includes embedded signaling fault detection. In one embodiment, the extended ECC augments the signaling fault detection capabilities of the signaling fault detection logic.
