Configurable-ECC: Architecting a Flexible ECC Scheme to Support Different Sized Accesses in High Bandwidth Memory Systems.

Designing error correction code (ECC) to guarantee strong reliability for high bandwidth memory (HBM) is imperative in high performance computers, especially for systems equipped with graphics processing units (GPUs). The design of ECC is challenging because future GPUs are expected to implement a memory subsystem supporting fine and coarse-grained data accesses to match the difference in the spat...
