Abstract :
Although it has been shown that cosmic ray neutrons play an important role in soft error (SE) phenomena, some important issues in neutron-induced SE phenomena are still to be clarified. In this paper, neutron-induced multiple-bit SEs in 16 Mb DRAMs are investigated numerically using the Neutron-Induced Soft Error Simulator (NISES), and simulated results are compared to experimental data. Scaling effects on multiple-bit SEs, effects of configuration patterns on double-bit SE rates, and the influence of multiple-bit SEs on an error correction code are discussed
