One memory-logic-integration design platform is developed in this paper with thermal reliability analysis provided for 2.5D throughsilicon-interposer (TSI) and 3D through-silicon-via (TSV) based integrations. Temperature-dependent delay and power models have been developed at microarchitecture level for 2.5D and 3D integrations of many-core microprocessors and main memory, respectively. Experiments are performed by general-purpose benchmarks from SPEC CPU2006 and also cloud-oriented benchmarks from Phoenix with the following observations. The memory-logic integration by 3D RC-interconnected TSV I/Os can result in thermal runaway failures due to strong electricalthermal couplings. On the other hand, the one by 2.5D transmission-lineinterconnected TSI I/Os has shown almost the same energy efficiency and better thermal resilience.
