   Abstract:
   In this paper, we introduce Jenga, a new scheme for protecting 3D DRAM, specifically high bandwidth memory (HBM), from failures in bits, rows, banks, channels, dies, and TSVs. By providing redundancy at the granularity of a cache block rather than across blocks, as in the current state of the art Jenga achieves greater error-free performance and lower error recovery latency. We show that Jenga's runtime is on average only 1.03 the runtime of our Baseline across a range of benchmarks. Additionally, for memory intensive benchmarks, Jenga is on average 1.11 faster than prior work.
