The Memory Wasn’t Up or Down. It Was Partly Serving
A threshold-pruned reliability model represented full, reduced and zero HBM bandwidth while retaining far less state.
Summary
A threshold-pruned reliability model represented full, reduced and zero HBM bandwidth while retaining far less state.
The proposed framework treats each high-bandwidth-memory service unit as multistate rather than simply working or failed. On a 14-unit incommensurate benchmark, its threshold-pruned traversal visited essentially the same state space as a comparison dynamic program but retained 17 entries instead of 412,121 probability states at central demand. A shared-stress model also showed that ignoring dependence could overstate reliability by 8.73 percentage points. These are exact model calculations, not field failure measurements.
Why it matters
